I recently got a double barrel break action pistol marked Casa Paulino Garcia Rio De Janeiro at a gun show. It's marked cal .380 L. I was wondering if anyone knew anything about it? a 9mm cartridge fits in the chamber, but does not engage the extractor, and a 38 S&W will not seat. IT's a non firing weapon, but I'd like to know what it used to fire. What era it was from and who sold it, as there are no import marks.
