Thanks for the gun porn, my favorite kind. Your "K" series can be narrowed down to 1957-58. I am assuming the stock
is the forced match serial# part since the "K's" usually came with a laminated stock, but the hand guard is solid wood, which leads
me to believe your gun originally came with a solid artic birch stock. The blued blade bayonet is most likely not original to the gun
since blued Bayos were early production 1950-51. The most common import mark is on the right side of the receiver, but early imports
had the import mark discreetly placed either under the gas tube on the barrel, or on the front sight base. I won't comment on values
since they are ridiculously ballooned and all over the place. Your SKS was refurbbed as marked on the receiver cover, but it was a very
light one probably just a replacement stock. No BBQ paint or grey rear sight leaf is always a good thing. You will most likely find electro penned serial #'s on the op rod, gas tube. ejector, under the rear sight leaf, and sometimes on the metal butt plate, that will indicate original parts to the gun. Overall a very nice Russian SKS and appropriately named.
