It's definately a cobbled up gun when it comes to a model twelve. The receiver is marked trap but has a skeet barrel on it according to the brochure. Could have been a 2 barrel set but the number on the extension tube is highly buffed and the wear doesn't match the receiver number. Also of a different size and may have been engraved to match the receiver number. It looks like a later 3 pin rib and serial number which would put the production date in the late 50's or early 60's. I would have to check the books. The wood is not original Winchester and does not look like it was fitted to this gun and so was probably added after the gun was originally manufactured. If it were mine, I would look for a minty original set of Winchester A or B carved wood. Hard to find though.
