Emirate of Bukhara, Uzbekistan, 1918, prior to absorption into the USSR. I believe this is KM-48. I am selling off my one per country collection formed over 20 years ago. Purchases were from reputable dealers. I combine shipping for winners of multiple lots at no additional cost, so please look for my other auctions. If you're looking for a certain country, let me know and I'll get it listed for you!
