Here's the story, I've come into possession of a Winchester Mod.68 purchased in 1916 by my buddy's grandad. It does need some TLC which I'll get to this weekend, but aside from some storage dust and a little light rust here and there, it's in pretty good shape. I may even take off the varnish, which I doubt is factory original, and just do a good oil finish. Here's the part where I need some feedback from those in the know. Firstly, what's the market value of this rifle, and secondly, who has ever seen a rear sight like this one? It's an adjustable peep with a wheel for elevation and a graduated tongue for windage. There's no makers name, just "USA pat. pending", so I don't know if it was a special option from Winchester, or an after-market additon by the original owner.
