Has anybody used these scopes, or know anything about them? I just inherited my Great-Grandpa's rifle (1951 Winchester Model 70 in .270win) and it has one of these mounted on it. All I've been able to tell is that it is a fixed 4x made in El Paso, TX.

I'd appreciate any info you could give me about the scope. I'd like to know the background of the model. I found it referenced as a sniper's scope at some point in history. Does it make for a good hunting scope?
