Yea, not an Izhevsk Arsenal but a "K" lettergun 1957-58. Looks to have the original laminated stock too. Does not look to be re-arsenaled, but if it was, there would be a re-furb mark in the shape of a diamond on top of the dust cover or a square with a diagonal line inside, on the right side butt stock. Hope you didn't pay Izzy price for it.
