I picked up this 36 a while back for around $200 because most of the bluing was worn off and it had some rust. The frame lug was also loose, so I replaced it. The action was still tight.
I stripped off the remaining bluing and sanded it down to about a 400 grit. As you can see in the picture it's down to bare metal. I'm now in the process of "rust bluing" it. It's turning out pretty nicely.
