According to a Facebook Page, Russian Look, this is what was found in a warehouse.

In the Russian warehouse tens of millions of working units of military weapons. Weapons of the Second World War, not much, but it is also millions in excellent condition.

I find the claim of tens of millions to be a bit hard to accept. Perhaps if they had a photo of the entire warehouse or at least showing multiple crates then maybe it could be plausible. Seeing what is in the crates is exciting though. I wonder what they will do with these?

Some PPSH-41s

Crate full of TT pistols.

More PPSH-41s.

Oodles of TT Pistols.

MG34s.

MG42s

AKs and possbily Nagant Revolvers.
