Thankyou very much for the attachments. You see, I'm planning (Possibly, I hardly ever forfill all these diorama promises) on doing a small scenario, where a group of deserting soldiers and sailors, fresh off the Aurora, meet in the streets of Petrograd, 1917.
Russian WWI & Soviet WWII are very similar, but not identical. For example, russian cap "beskozyrka" had 3 white pipes, but soviet - 2 only. Shoulder stripes were canselled in april 1917.
Uniform depend from time and season. If you wish to see any films, best: "We are from Kronshtadt" or "October"
