Stith Rear mount and ring for Winchester 70 and 54

I have a rear mount and ring for the Winchester models 70 and 54 with a 1" ring. Unfortunately I can't find the front tube. In very good condition, all screws and ring are strong and tight. No buggered up screw heads Fits the factory drilled holes on the left hand side of the receiver. Hole spacing is  .600" and can be moved ahead or back as there are three mounting holes.

Will ship but will be $15 as I won't be able to send it lettermail.
