Jerry - I looked at that one - it is pretty old - I'd guess mid-60s - but I'll be darned if I can see what's so special about it. The tension nut is unusual, as are the perforations, but other than that it looks pretty ugly. I've got two VERY nice 88s, both of them have chrome rails and the aluminum cantlepiece (which is what differentiates this model from the 90). Even the "big rivet" one I only paid 100 bucks for.
I guess it's all about how bad a bidder wants it. Lucky seller!
