What it is
A Paterson Super System 4 tank for daylight processing: two 35 mm films or one 120 at a time. It comes with two reels that wind the film in by themselves — ball bearings in the guides draw it along as you twist the reel halves. The large rubber lid seals the tank, so it barely drips when inverted.
What it fits
Paterson and AP reels are interchangeable, so the tank also takes AP reels you may already have. It needs slightly more chemistry than a JOBO 1520 tank of similar size.
One practical note
Press the lid home all the way round until it seats — then the tank can be inverted without leaks. Load the reels only when dry.
