I picked up an SVT at a local gun show about 3 yrs ago that looks much like yours. Couldn't pass it up at $200. I put one of my after market magazines in it and sold the original for $175. I put flat head screws in the holes and shoot it as intended - with iron sights - shoots great. It also had a $15 M1icon Carbine sling on it which I put in my selling pile.
I may now have about $40 total in the rifle. Makes a good "Cheap" shooter!!!
