It looks like a nice rifle. It is WWII era, it was made in 1940. It just has mis-matched parts which isn't unusual. Obviously doesn't make it a top notch collectible but these are going up in value all the same.
It doesn't look like it has the Russian Capture "X" on it which most coming out of the Ukraine have. Import mark is usually near the end of the barrel. Russian captures will also have a serial number stamped in the butt stock and usually electro penciled serials on the major parts.
Does the stock have the eagle markings intact?
dont notice any markings on the barrel and dont see any on the stock.
oh well.
