  1. GM 5+ SE is sold. Only Pirate Black Pearl remains...
  2. Not sure why these photos are posting upside down!? Actually, I would typically mount the Cobra II upside down on the rod as shown (but a bit farther out toward the coil) so that the center of gravity is lower and my trigger finger is closer to the controls. A great George Payne design, albeit beaten with the ugly stick! Note the dual range disc on the 1650. At one place I lived in VA, the builders must have spilled a box of galvanized roofing nails off the roof and they were spaced every six inches or so, All machines I had went crazy over that, but the 1650 only made a few extra clicks and pops and actually picked out a few non ferrous targets in the thick of it. I got the 1650 with a 10"coil, totally not what I would use with this machine, One day I was detecting in Texas and the bottom cover of the coil fell off and blew off a cliff! It is basically a 15kc Tesoro-like circuit and supposedly the old brown Tesoro donut coils will adapt with the proper connector. Also Garrett Scorpion coils are said to work but might have to flip the phase of the TX winding.
  3. Well, I figure people looking for these old and/or offbeat detectors already know what they are. All of the modern "menu" detectors look pretty much the same in pics anyway! Check out the many you tube videos on GM5+ SE and "The Black Pearl."That Pirate machine air tests like mad. https://www.youtube.com/results?search_query=pirate+the+black+pearl+metal+detector If one doesn't already want a Bulgarian knockoff of a well=known Russian DIY machine, a mere photo will not make the sale! See also the many incomprehensible but interesting vids on Russian "Fortuna" or "Fortune" detector. It has some very interesting features. Still trying to figure everything out. i 'll get some pics of the GMT-1650 CEC. That detector is an oldie famed for unbelievable lack of masking in iron and rusty tin. Blew my mind many times. Doesn't go deep though. It was a spinoff of the more common Gold Mountain Cobra. Well known and regarded machine in some circles. Seldom seen...don't think there are too many around. I got mine 25 years ago in Texas. Hard to sell that item to somebody who doesn't already know it and want it! Best discussions on the GMT-1650 occurred on JB's old detecting site around 2000 and I saw some of this material archived on the Wayback Machine not long ago. Discovery Cobra II was hot around the same time frame. JB's was a good place to learn about those also. Closest modern machines are the analog two tone Vistas, Smart + and such, but the Cobra II had far superior disc to the Smart + in my experience. You can crank the Smart + up a little more but the Cobra II was a bit more stable at its designed power level.Somewhat unbalanced and unwieldy but a great detector. I'm listing thus stuff here because I know that all the hardcore maniacs stop by Steve's site, my target demographic! I can understand that buyers would like to see pics to make sure I actually have the machines I'm selling and I am certainly happy to provide them on request.
  4. Moving deep down in the concrete jungle, downtown Philadelphia, where there is almost no visible dirt, so I'm downsizing my collection. Guess I'll keep a Rutus and maybe one more in case opportunities arise. Here are a couple specialized and offbeat machines that would be of interest to denizens of this forum, which is why I'm listing here first. Pirate "The Black Pearl" basically a "Fortuna" with Bulgarian accent and pirate garb. New in box, pretty much. Quite interesting machine that I never got to use beyond bench testing. $200 plus shipping Golden Mask 5+ SE-- Two coils. Also basically new in box. $300 Gold Mountain GMT-1650 with 4" coil only. Rare. Was hard to find 20 years ago. SOLD Discovery Cobra II with two coils--5" and 8", GB and Sens knob mod. Always a fave. SOLD Have a couple Tek Mark !s and a Mark 3 from project to modded on White's rod. If I could only have one, this might be the one to keep. eh? Inquire if interested. Contact me for pics and/or further information. Location Washington DC. Buyer pays shipping. Paypal preferred. Joe
  5. It sure would be useful to have a few degrees expanded disc on a Smart to knock out foil. Last time I had my Smart + out I was in a wooded area within 100' of a highway and I dug unbelievable amounts of foil- tiny bits of cigarette and gum wrappers, pieces of Red Man chaw bags. Some tiny foil at some depth. Small foil hit pretty good too. Impressive in a way but I felt somewhat defenseless in an area where it seems wind and topography concentrated this irksome road trash over the years. Granted, it is not intended as a trashy park detector but a bit more upper range disc would greatly enhance the unit's flexibility in areas of modern occupation. Aside from that, I really like the Smart+....and I don't really mind the funky big box look, although the new box does look a little more up to date. And it is nice to have the Super Six coil, a great setup around iron.
  6. Yeah, Mike, a 16' piece of PVC would be like a noodle even without weight on the end! I'm just offering a solution in theory....but you know what Yogi Berra said about theory. Now if the tape is moving, you should be able to pick a more convenient spot to measure, say 1' or 2' out the innermost point of travel of the tape. If it is moving, you should be able to detect movement at that point. Sounds to me like it is not moving though, sadly, if you are not seeing any change in resonance.
  7. Obviously, you could have the control head near the search head, using the current cable, then extend the audio cable. Low impedance audio line can run 24' easy and then you would not have to worry about RLC of the long search coil cable interfering with operation. Plus you could use any old cheap 2 conductor wire.

  8. Thanks for further comments @2valen! i searched numerous full text databases: 18th c British periodicals, 19th c US newspapers, three or four academic journal full text libraries, and nada on "Joy of One" or "Joy of 1," aside from various citations of the two instances I noted above. Don't have full library digital access anymore, only limited alumni access, but I can usually dredge up a few references on almost anything that way. Wine industry in NY started mid-1830s in a small way but got serious and grew tremendously beginning in the mid-1860s, even though NY State was a grape growing region before that. This is one of those artifacts that caught my eye. Strikes me as a very poetic phrase and intriguing item that speaks to me...now I'm just trying to figure out what it is trying to say!
  9. C'mon 2Valen, spill the beans on the details on what you know, OM! That's what crowdsourcing is all about There seem to be Victorian era glass seals intended for sealing letters. My feeling is that the emergence of glass seals had to do with technological improvement and manufacturing economics rather than any particular practical advantage in glass, aside from colorful looks. I have seen impressed pottery and pipes, and even wine bottles (glob of glass with seal impressed on body), but never saw any original seals for this purpose. One reference I found speaks of brass or molded clay bottle seals. Glass would seem to be a sketchy material to use to stamp molten glass. I am not sure of the historical antiquity of wax seals on bottles, which is common even today (although the modern seals are probably all plastic.) This seems to be a poor mans version of the all glass sealed bottle, which stems back to at least the 17th c. and show up profusely in the archaeological record of the Colonies. Tanqueray gin has a red wax (plastic) seal on the front of the bottle, for example. A touch of class, eh? Here are some pics of glass seals from Colonial Virginia: https://mesda.org/exhibit/wine-bottle-seals/ Those are very prominent names in Early Virginia. Bottle seal database: https://www.cova-inc.org/wineseals/visual.php Another overview of the bottle seal: https://apps.jefpat.maryland.gov/diagnostic/SmallFinds/BottleSeals/index-bottleseals.html Some interesting artifact background stuff on that site, BTW. ---------- As for the "Joy of One" motto, I found two literary references using that term, one a stanza of Wordsworth, commenting on the post revolutionary esprit of Calais of the one year anniversary of the siege of the Bastille (1790) "How bright a face is worn when the joy of one / is joy for tens of millions" And an ancient folksong, collected in Connecticut but seemingly of old British origin, "The Joys of Mary"--usually framed as a Christmas Carol "The first joy that Mary had, it was the joy of one, To see her son Jesus in the world to come"
  10. Yes, but ROY was a common spelling for the French Roi in that period also and that is one French word that most educated English speakers would have known. I am not sure that that is an "I" on the seal. Looks kind of FAT for an "I" or even "J." Closer inspection might help narrow this down. Does "Joy of I" make any more sense than "Roy of I?" Maybe it is a literary reference? Otherwise, it is a bit odd either way, I think. Perhaps the scene depicted might offer clues? As for glass being shown on that page, are they?...or are they agate, carnelian, and other stones? Glass would be molded, I believe, whereas stone would have had to have been carved and engraved in reverse bas relief. Most of the seals on the page supplied, especially earlier Georgian ones, do not appear to be transparent in the manner of paste glass. My thinking is that mass produced glass items would be later and cheaper than artisan-crafted earlier versions. If "mass produced" then the wording must have had some general currency beyond a weird one off. Who would buy it if it was weird and senseless? Are the glass seals French or English made? They were more common on that side of the Atlantic for sure. In 18th c America, I'd think a seal would be something that only rather wealthy folks would possess, whereas a democratization of the manufacture using molded glass would open up the market a bit. Anyway, this is all hopefully productive speculation on my part, as I am no expert on wax seals. I'm interested in that artifact though. Studying historical archaeology in graduate school, I developed a tendency to spin inferences and strings of questions to check out via further research, often based on little or no preliminary evidence! 😎 Gotta start somewhere!
  11. If French manufacture, perhaps it is a code-mixed expression "Roy of I (or 1) from Roi for king. King of my own castle sorta expression. One man riding free. I venture this interpretation since the only glass seal on the page from Pimento has a Fleur d'Lis motif which put me in a French mode. 2Valen's point about seals on bottles of wine is a good point. Seems commonly done in 18th c. America.
  12. Post a pic! Very interesting artifact you dug up there. Many of the Victorian wax seals are whimsical designs, but throughout history seals were used for important purposes, such as marks of identity and legal authority. A lot of the British/European seals have heraldic symbols on them, but there was a lot of "fun" stuff too, especially through the second half of the 19th c. Did you find this in the States? We don't really do heraldry here~~~ Once. when i was working in a used book store in Philly, a snooty old lady asked in an affected English accent if we had any books on heraldry, I answered, "Harold Ray? Never heard of him." 😜
  13. That's obscure! Maybe a variant typography of "Joy of I" --which is still a bit of a puzzle. If you can find some sealing wax or even modeling clay, make an impression. Appears to be an interesting design with horses and whatnot. I think the technology goes back to Ancient Babylonia. I know I have seen Roman seals in an archaeological museum. If that one is made out of glass paste, i'm tending to think it is late 19th century...just a seat of the pants estimate. Perhaps a positive impression in wax or clay will offer up more clues.
  14. Kac, Here's an extension cable for Tejon https://www.metaldetector.com/tesoro-4-pin-extender-cable\ https://www.seriousdetecting.com/product/tesoro-5-extension-cable-tesoro-delta-series-metal-detector/ Seems unlikely that they would use a custom connector....that sounds like an expensive option to pursue for no good reason. Also, Cors makes aftermarket coils so where are they getting their parts? Vintage US connector companies usually have the name molded into the plug somewhere. Some old radio mics used a 4 pin Switchcraft slimline connector like that, used to be called a 2504M. Maybe the old style has the features you need. Here's a pic of an old style 2504....has a flat side whereas the current 4 pin slimline does not. https://www.ebay.com/itm/SWITCHCRAFT-2504M-SL404M-MICROPHONE-PLUG-FOR-BROWNING-GOLDEN-EAGLE-MARK-IV-NOS/153871087788?epid=1901928907&hash=item23d36e78ac:g:3HwAAOSwzrZedC6f Still the extension cable is not a bad deal, it's guaranteed to work...and you get the wire with it! To me, finding the plug wouldn't be the hardest part of making a good coil! Sounds like a fun challenge, and I have built a lot of electronic gear, but i'm happy these days if I can simply go out and buy what I want!🏧🌈
