I traded the Yugo SKS i had for this. The serial number on the receiver 1135 is on all metal parts except the bolt which appears to match itself. the stock is apparently a Yugo capture (ironic) and is completely unmarked except for a small "M" on the top right behind the tang of the receiver and "br" under the buttplate.
