Sears never "made" any guns! They had others make them, then put "J.C. Higgins" or "Ted Williams", etc., on them.

With the limited information you supplied, my guess is that you have a rifle built on a Belgian FN Mauser commercial action, or possibly a Win. M70 action, with a barrel and stock made by High Standard. In all liklihood, it was made some time from the middle 1950's to the mid-1960's. (A picture or a description of the proof marks would have helped ID it.)

IF thisrifle is built on the FN Mauser action,it is an excellent rifle, well-made, and probably worth more than you paid for it as a hunting rifle/shooter, but still not as highin resale value as it ought to be!

If it is built on a post-64 M 70 action, it is not as desirable as the Mauser action rifle would be.
