If anyone is interested, this is what a 99+% C-96 looks like. The entire inside of the pistol, is gooped in cosmoline, or whatever. It will never be fired.
I have been playing with Broomhandle Mausers since I got my first one, in 1971. I never looked back. I have two now, the one pictured and a shooter, which, as I have noted, has digested thousands of Tokarev rounds. I change springs every two thousand rounds, and it is critical to keep a close eye on the hammer spring. That is the most important spring in the gun, as the spring which initially retards movement. It has a pitted bore, but not a dark one. It can still hit an orange at 25, every time. I also keep a close eye on the barrel extension around the bolt stop, for peening or any deformation. There is none. I have magnafluxed it periodically to make sure.
I have gotten most of my information regarding the two calibers from the posts of Johnny C, who specializes in collecting those two calibers, belongs to an international cartridge collectors organization and has probably forgotten more about them than the rest of us will ever know.
