Just acquired a new TT-30 Tokarev, my first example after handling a few TT-33s. I noticed it has some interesting marks stamped into it, which I'm presuming are manufacturer's marks, but I couldn't find anything on them by searching. The deer skull symbol is particularly interesting, I've never encountered that. Could anyone please assist? I'd be very interested to learn, I'd like to start decoding all of the markings on my Soviet weapons.
