I have a few spare tanks I am not using. The First tank is a generic tank from Adorama, holds 2 rools 35mm or one roll 120. Comes with 2 plastic film reels, adjustable of course. No agitator, but everything else is there. $18 shipped. The second tank is an old Paterson tank system 4 tank (with a white lid). With 2 adjustable plastic reels. No agitator, but everything else is there. $18 shipped. I've used both but have gone with the standard Super 4 tanks in my dark room so the parts are interchangable so these need a new home.
