About collectors. Can't say about Russia, but I have have the feeling that is probably is same as in Ukraine - very few collectors as surplus firearm has limited availability, plus many years of Soviet rule killed gun culture. However there are some interesting researches and scattered information on public forums. I would say there is certain amount of ppl who love the history and research the history of firearm but not necessarily collect it. As for old folks who worked at factories - maybe someone from Russia could comment, I have no idea.
