Recently picked up a couple new cartridges for Pauly guns! These are a couple of the very first fully-self-contained cartridges.
The one on the right is a rosette that would attach to the bottom of a paper cartridge.
The one on the left is the one I had previously.
Also picked up a neat early publication from 1822 that has a lot of information about the Pauly system guns and a drawing by Henri Roux (Pauly’s employee and then successor.) You can see these pistol cartridges at the bottom left and the rosettes on the top right.
