Started cleaning it up the other night...the walnut was definitely something to see, once all the grime was off it. It's about half a tree. The bore cleaned up very well- once the spiders were evicted. The interior rust was more a dusting, hadn't pitted at all yet. Looked a little strange...could that be a gain twist? Nah...then I started looking at the barrel itself. Degrimed, I was finally able to see the small lettering on top of the barrel...."H.M. POPE". Good Lord! I turned it over, and sure enough, those mysterious numbers Mr. Pope always placed on the bottom of the barrel were there. I had bought a Winchester Model 52 with a POPE barrel!
I guess I'll take it to the range tomorrow without sights and function check it. After that...well, looks like a project. I really hadn't planned on it, but looks like this one's going to get restored. I have a feeling this is going to get expensive!
