Stupid me. I suppose since it is not marked Denver nor USA, it is likely NOT same. But...for all the world, it has the tube, bells, and turrets and appears at first blush to be a Denver Redfield. But the script is on a grey field, black letters and no markings as described.
Pretty clear glass, I suspect it is one of the early collapse Redfields with Japanese lenses using tubes bells from Denver. The scope was in a display with some other sure'nuff vintage Redfields, I shot the guy a lowball price and he took it, so I carried the thing home. Upon retrospection, not what I thought it was, but it'll do on an old rimfire, the Widefield lenses will simplify mounting, and the 'scope is from the same era as the rifle.
Oh well, live and learn.
