I was given one of these in a box full of old, musty items bought at auction for near nothin
Had to have sat in a basement for decades and then presumably the gentleman -Kodak employee and photographer- died

Thing is pretty neat. Had never seen one before or heard of
Holds 12 sheets of 4x5 or whatever format you may have

My questions
Does it work well or simply better than other cut film tanks?
Seems easy to load

Any idea on # produced?
Why are they rare?
