Russian/Soviet SKS made at the Tula Arsenal in 1953. The receiver, gas tube, stock, and magazine all have matching serial numbers. 

It currently wears a Tapco Intrafuse stock and uses detachable mags, but I have the original parts, so the gun can be put back to stock condition. I also have Tech-Sights model TS-200 aperture sights installed, which makes the gun far easier to shoot accurately. It comes with 5 x 20 rd Tapco mags and one 30 rd USA mag, plus a sling and a couple stripper clips.
