The longest lens I have is a 14 1/2" Ilex in a big #5 shutter.
There's a Turner Reich convertible with the camera, the front 2 lens elements came unglued, literally. No damage, I suppose I can clean off the balsam residue and try to re-cement, it's got a 21" rear cell, #4 Ilex Acme shutter that fires on 1/50 s.

I was kinda feeling down the last few days, this is has been a great lift to my spirits. I love this American workmanship it's so pleasing to see and touch. I need to get it home, hopefully this week.
