[QUOTE="480sparky, post: 484069, member: 15805"] .......... it would probably be like farm-fresh cream. At least with my latest acquisition: A 1984-era Soviet Tair 135/2.8 11-A T-mount preset. [IMG]http://i214.photobucket.com/albums/cc172/480sparky/Photography%203/Tair%2001_0699.jpg[/IMG] I scored a near-mint condition copy a couple weeks ago.
