I just wanted to share my deactivated Ppsh-41 and ask an quick question. Do you guys know how to get the thick gun storage oil off, without damaging the metal. It's such a pain . My friend told me how they had to grease Soviet artillery cannons with this stuff each winter and then again clean it in the spring, sounds like hell. Here are a few pics for you.

Heres the factory stamp and date, quite common.
