Is this the one with the near UV argon bulbs? Has more switches than a B-29? They used these in WWII for rush printing aerial film, big 10x ?
I know Morse made big long roll developing tanks for the USAAF.
I have a couple of Arkay Speed Dodge printers, one has the argon lamps, incredibly fast. Will expose slow enlarging paper in under a second, these were designed for high speed production work with slow silver chloride contact paper. Even with Kodak Azo, or Fomalux, Lupex expect 2 to 4 second exposure times. Those machines are beautiful because obviously you can switch each bulb independently. Be careful, wires may have a bit of asbestos cloth, maybe not.
