UPS did not find my fathers rifle. I need a price on a Sears J. C. Higgins Model 51 when it was new in 1951, and where I can get my hands on the proof. My mom no longer has the paper work, and UPS is going to give me a hell of a time. [:'(]I can find the current value for the model 52 and 53, but not for the model 51. Thanks in advance.
