One more Russian addition---
At a Montreal gun show in 2009 I bought this Russian Ssh-36 helmet-- 1939 dated.
I knew nothing about these helmets---neither did the dealer that I bought it from.(Who I knew very well.)
All of my research came from the War relics/European Forum.
Some of the comments I got.
RUSSIAN HELMET
This is what I learned on the Forum about the Russian helmet shown below....very helpful.

Forum response from Michael Baskette –former U.S. sales manager for Ostfront.
The helmet is an interesting example... It is not an M39 liner exactly, but what you might call an M39 style liner. You find Ssh-36 and 39 helmets from time to time that have been relined with this liner system. While superficially similar to the Ssh-39 liner, they are not constructed the same as a factory Ssh-39 liner.
Why were they relined? The helmets were relined due to damage or having the original liners removed for winter wear. These liners are all very similar in construction and material make up. Likely they were all done at a single depot location. It is possible that because of the use of crude material and the non-standard construction and installation that these type helmets were relined in Leningrad during the siege.
The Siege of Leningrad.

On the Forum a fellow named Dimas (a moderator who I think is Russian) added the following;
I cleaned up the English a bit.....I hope that I did not distort his thoughts?
Michael is right, most of these helmets were relined in Leningrad, during the blockade, approx 5000 helmets were redone, the helmets were removed from recycling, and due to that all the liners were removed before sending them to recycle. Then due to absolutely no resources in the blockaded city all the liners were made for both German M16 helmets (very rare reissue),SSch-39( surrogate copy of SSch 39 helmet - tin made in Leningrad) and other helmets which were sent for recycling battle damaged Ssch 39-40 and Ssch 36 and M15,17 and other helmets.
Your is typical Leningrad redone. They are very rare, they were found in one of the Leningrad's factories in an air protection bunker approx 500 pieces (5000?) In the Soviet time all of the factories and even the ones for civil houses had air protection bunkers, but only the factories had the helmets, due to the needs of the factory guard in war time.
When I was a child it was a nice adventure to go to those bunkers through the ventilation system to get some gasmasks and military wear.

I am not sure how accurate my modifications are to Dimas' comments ....but hopefully you get the drift.
