Coating to prevent rusting

[Went Blakely]

I would agree with Ron, that's what would give it that rather interesting phosphate finish. I would just lube it, and keep it oiled and leave as is. Great looking piece with history imho

Got pistol back from local gun shop. They test fired, disassembled, cleaned, fired again, "gently" removed surface rust, and sprayed with a silicone coating (see photo). We took forums advice on not trying to refinish for which I am grateful. Keeping it oiled in the future is the plan.
Now I have another question/problem. On both test fires the gun would not re-****. I read and copied the forum thread which sounds like the same problem (?). Everything else works fine but have to manually operate the toggle to fire next round. The local guys recommend that I find somebody who is more of a luger specialist. I am on the SC coast half way between Charleston, SC and Savannah, GA. Willing to do some driving but do not want to attempt the repair my self nor am I inclined to ship the pistol. Hoping someone on board can recommend someone in the area.
Again, all past help is greatly appreciated. Still having fun.
