ID Help - Pewter Flatware

[rod-pa]

Hiyas...I recently dug a part of a pewter flatware.  I have never seen a makers mark or other identifying mark on flatware that I have dug before.  Putting it under my scope, and fooling around a lot with lighting directions, this is about the best it is going to get.  Any one have access to pewter manufacturer information?  I am stumped so far.

The bottom is METAL, the top left looks like a B or S to me, and the right side I believe is NTA

Wondering if it says Britannia, with the misspelling of the last "I" with the "T". If the missing top piece was there, we would see if the first "I" was there or a "T" was used. Google Britannia metal and it was widely used.

Does look like Brit 8 over a hallmark. I would look up hallmarks rather than makers marks. Seems really rough for pewter. Tin is usually pretty corrosion resistant and over time the brit 8 turns a little dull gray but brighter than the leaded pewters.

Brit 8 came out in 1769.
