Glad to see that my search for a Winchester Model 97 turned up a thread that's not too old...
I, too, have a Model 97, built in 1927. My dad tells me he bought it from "some guy", and never fired it. While it shows a cracked hard rubber buttplate, some missing chunks of wood around a couple of edges and some scratching around some sharp edges on the left side, it looks remarkably good for a 83 year old gun.
The story goes that the model name was changed (from 1897, to Model 97 or M97) in the early 20's because the marketing gurus thought no one would buy such old technology from the "last century". Fact is, it's one of the first to shoot the new smokeless powder...what we use today. This makes it even more valuable.
