Hello All.
I am not familiar with the world of Imperial Russian Headgear, and I am interested in a piece for sale that I am unsure of, and would like some advice from one of our member witch are more educated than myself. I'd like to just exactly what this piece is, and if it is original. I thank you in Advance, Gentlemen.

Ah yes, a general price range for this cap would also very much be appreciated, so that I can know if the price the seller has on it is good.
Again, thank you in advance.
