I'll give the thread a shift to the east with some of my soviet gear:
Soviet armoured officers Gymnastroika, 1935 pattern (sadly a repro):
Wartime naval officer shoulder boards (pogoni), on the left an original for senior officers and on the right a reproduction of the shoulder board for a junior officer that I produced:
Soviet naval officers tunic for junior officer serving on a submarine:
On the left, original wartime soviet ushanka (fur hat) with synthetic fur (called 'fish fur' by soldiers), it has never had a cap star as it was worn by a POW who also took off one of the ties on the ear flaps and put on a button. On the right is a Bulgarian ushanka.
Tank crew jacket:
There is more, really should photograph the lot one day.
