No there are no markings, exept for two labels, one in the tunic and one in the trousers. I guess they are only the manufactures labels.
the right pic is from the trousers.
Is it jacket only? If it was a complete set with cap, trousers, belt etc etc. I am sure it could generate a few houndred USD (there was a Kremlin guard cap at e! that was sold for 300 USD) but just the jacket... perhaps 100-150 USD?
