Could be wrong but that French looking helmet is a Russian 1936 version whilst the others are 1940 types. Another variant that could be worn is the Russian version of the Adrian helmet still worn in 1940. As a point of interest the Russians also wore the British pattern helmets in some capacity.[8-)]

My major complaint is that Phaisal posted TWENTY photos when three or four could have easily shown this diorama quite adequately! The dial-up internet guys won’t even try to load this post!
