One of the many revolver systems designed to work around the Rollin White patent was the Pant’s Patent cupfire revolver, made by Merwin & Bray in several calibers (.28, .30, and .42). This particular example is a nice on in .42 (which is the diameter of the cartridge case; the projectile is actually .39 caliber). The cupfire system was similar technically to rimfire, but with the priming compound in the base of the hollow cup at the end of the cartridge case. This allowed it to be loaded from the front of the cylinder, and fired by a hammer striking through a smaller hole in the rear of the cylinder.
At Forgotten Weapons I think the most interesting guns out there are the most obscure ones. I try to search out experimental and prototype weapons and show you how they work, in addition to more conventional guns that you may not have heard of before. You’re much more likely to find a video on the Cei Rigotti or Webley-Fosbery here than an AR or Glock. So, do you want to learn about something new today? Then stick around!
