Here are some pinfire cartridges from South America. Are there others? (specifically looking for metallic cartridges rather than shotshells but would be interested in seeing those too.)
These were made by Sociedad Anonima Spreafico (same company that makes the SAS headstamp on rimfires) - Buenos Ayres, Argentina for Carlos Rossetti, a renowned early gun manufacturer also in Buenos Ayres. This is the 7mm and 9mm example.
Made by or for Bertonnet & Gobert of Buenos Ayres, Argentina which was a gunmaker with a shop at 50 San Martín Street across from the Metropolitan Cathedral. This is 9mm.
I am not positive about this one, but it at least says Buenos Ayres on the bottom and I think it may say something like Bertonnet y (and) Gobert at the top. This was excavated from a Confederate encampment in New Kent, VA which saw action in the American Civil War as the Union army made their way to Richmond. This is a 16g.
Fede, what’s your take on this one?
