This came along with a recent purchase and, as I already have a boxful of finders, is available for $50 including postage.
Optics look clean as does the outside. I have never used one so What you see in the picture is What you get....
Cheers,
Matt
The beautiful book "Full Moon" that the finder rests on is
not included in the sale but is thoroughly recommended viewing for Apollo Program enthusiasts, superb book, one of the best series of lunar exploration pics I have seen to date...
