Ok you scope experts help me out here. I have come across an old scope that I have never heard of and have a chance to buy it cheap. The scope is a 4-10 power, constructed of steel I think as it is sturdy and heavier than modern scopes. It is a one piece tube with caps on the adjustment wheels that are like none I have seen and a little difficult to describe. It also has a focusing ring on the eyepiece. The reticle has three heavy posts on the sides and bottom with a very fine wire post on the top. It is extremely clear and bright. On the side of the scope it says Supra 4-10 variabel -made in Germany. On the eyepiece it has the markings Nikel- Memburg. Any one ever heard of these scopes? any idea of value? Thanks!
