Salt Flat
I had accompanined a friend down to the outer cape (Cape Cod) he was going to look at a .22 this guy had, while we were there he brought down a bunch of stuff that he had in the attic. It was all rusted, some really bad. The salt air their is tough. anyhow, the Luger was in a P-38 holster and when I looked at it it wasn't rusted! It did have the bottom back corner of one grip broken, about 1/4 inch of the corner gone, just enough so you could see the mainspring. The Arisakaicon had a light coat of rust. He wanted more than $500 but I dropped 5 $100 bills on the table and said 500 if he threw the Arisaka in, since it had rust it wasn't worth much, I had no clue don't collect them. He didn't want to but he took the deal, I got lucky! The Luger is an S/42 from 1939, slide all matching (17) and frame all matching (71) but really nice other than the grip.

On the Arisaka I took some WD-40 some OOOO steel wool, and a rag and the rust came right off. I then oiled it up.

One thing about it, after cocking I pull the trigger and it clicks but unless I put a little pressure on the back of the bolt it doesn't go forward, wonder if there may be some rust in there?

Oh and his father had brought it home from WWII and had decided to sporter it.
