These have been posted before, but it's kind of nice to have all in one place. First two are of two different Pauly guns from about 1811. These guns, both in rifle and shotgun, had a copper centerfire cartridge, internal hammers, and an exterior cocking lever. About 50 or more years ahead of most other outside cocking lever guns.





This is a William Moore and Grey gun with the Grey Patent. Cocking levers look like pinfire hammers, but the strikers and hammers are in the interior.
