Back when I was in the business in the early 80's, a Coast Guard PO stationed in Galveston, brought me an old original Winchester 1886 in a pillowcase and cigar box. He had a neighbor that gave it to him thinking since he was in the Military that he could put together any firearm. His neighbor told him that he had mostly taken it apart to clean in and it was more complicated than he thought, so he put all the small pieces in the cigar box and all the bigger stuff in the pillowcase.

Funny thing...as far as I could tell, he didn't clean a thing.
Anyway...I gave him a price to clean and reassemble (I think ~$35 bucks back then) with the caveat that any missing parts would be extra. He hemmed and hawed but finally agreed. I had one quick thought to offer him a hundred bucks for it, but didn't. Every single part and screw were there and in good shape. I almost couldn't believe it since his neighbor said he hadn't touched it in almost 20 years. It cleaned up nicely. It was a 33 WCF, which I didn't have and kind of kick myself for not offering the guy the out.
I did notice the OP has not been back to visit since his initial post though. Another Drive-by. This site seems to get tons of them.
