The NOVA Darkroom processing tank is a key piece of equipment for processing black and white prints. This is a great system for reduced space and efficient use of developing chemicals. This particular unit was purchased and never used due to circumstances and has been stored carefully since purchase. The unit has 4 slots, the tube lids and two clips for holding the paper between tank slots as the print is being processed. It is as new and probably a rare opportunity to acquire this piece of equipment.
