This is a good teaching project. Unless I am mistaken and its truely a dog, all the repairs will be home amateur handwork somewhat as follows Shorten barrels and fill gap Long forcing cone Polish bores, chambers Fix safety Put barrels back on face Fix trigger guard Replace springs Fix small crack in tang Fix crack in forend Refinish forend Replace buttstock Refinish buttstock as needed to match forend finish Add bead and fiberoptic sight Brown or blacken barrels Brown or blacken action Add sling swivel mounts Shoot A rattle trap of a Stevens 5100 12g. Literally, rattles! It comes disassembled for a reason. A very early gun, the forend wood should be repairable, one small crack.....the buttstock has old putty repairs, missing wood and a long central crack, likely from some one falling across or using the gun as a pry bar. Action was long ago reblued purple. We'll fix that, rust black. The safety detent is missing in action. The top snap spring is long gone. The right firing pin is so dirty it sticks. But, the essential functions are there and I believe it'll be a fully functional action with new springs, inspection and cleaning. A small crack in the action.....not worth welding. Probably caused by the trauma that broke the buttstock. I'll stop drill it and silver solder the remainder....should be right as rain....its a non critical area and less than one third of the width of the lower tang is penetrated by the crack. The bores are sewer pipe dirty. (But upon cleaning, lovely and essentially pit free. They'll need polish inside but no dents, no rust and came out bright and excellent with a bore snake only) After the old reblued, someone tried to drive out the hinge pin since this one is loosie goosie. It didn't work, not because they punched the wrong side. but because these guns have a pin to be drilled out before you drive out the hinge pin. I'll fix it, tight like new. Barrels shortened to 18.5" before final finishing to length. A snap on light pipe sight will sit behind a traditional brass bead later. Should be slick when done. New buttstock will be needed. Springs and bead are in bound. I'll make the hinge pin and we'll fix anything in the action that's worn out. Barrels will be browned. Action Rust Blackened.
