Recently purchased a Turkish rework Gew 88/05 made by Spandau in the 1890’s. It’s complete save for the front band screw. Stock only has one small chip along the top of the fore end and the usual dings and dents from being 131 year old service rifle. I’m going to disassemble the rifle and swap the barreled action with one from Loewe that has a nicer bore and better finish. As for the metal parts from the Spandau that I’ll be reusing, some will need to be rust converted by boiling in distilled water and then carded off. I’ve done that before. But this stock is grimy. I mean GRIMY. Has to be the dirtiest milsurp stock I’ve ever purchased. I’d like to clean it up as best I can without doing too much damage to the oil finished stock underneath all the crud. Any suggestions on how best to do this?
