I agree Dave.
It's a lens I suspect very few have ever seen. Only 3,000 were made and they were split up between Canon, Nikon and other makes.
Tamron SP Adaptall-2 180mm F/2.5 LD-IF Model 63B
I had the chance to buy one many years ago but just couldn't pull the trigger as I believe my wife was standing beside me at the time.

I do recall it was beautifully made and felt just perfect in the hand. Feel is a subjective thing of course but something I think is important if a lens is to have "legendary" attached to it's name. The review above indicates it was a brilliant performer as well. I later got a K 200/2.5, which also has great feel, and never looked back. I still wonder how the Tamron SP 180/2.5 would compare with the K 200/2.5. Anyone out there have both?
