Soviet RKKA General or Bulgarian - or neither?

[deValcourt]

I asked the seller about this belt buckle and mentioned that all of the GPW and earlier officer belts I saw have a similar studded belt, but the buckles were a star with "rays" inside the arms and a central circle with a prominent H&S and this is all a cut-out design from solid brass. I actually have one of these old buckles (alas, no belt with it) so I asked him where this one was from.

The seller says: "...this belt USSR Russia General" and the listing says RKKA. Anyway, I still don't recall seeing these in the Soviet army, but uniforms are a relatively new interest to me (and typically just a specific set of organizations' uniforms from certain periods).

Anyone know anything about this? Since the seller says he's in Moscow, I don't see how he can sell this or many of the other items he has listed legally...if they are authentic.:(
