Maybe a long shot. I have two Paterson Super System 3 reel tanks both missing the cover/lid - the part that you attach to keep the liquid from pouring out. I must have left it somewhere to dry and then discarded them accidentally. They are not for sale as parts apparently. I don’t want to spend the $35 for a new tank. Anyone with an extra lid? I don’t mind buying a used tank with the lid but these things are bulky to ship safely.
If you can't find them here, Freestyle sells parts for Super System 4 tanks. They sell the lid and funnel together. Still cheaper than a new tank. Type "Paterson" into the Freestyle search box, or https://www.freestylephoto.biz/1420...tem-4-Tank-Top-Lid-and-Funnel-Replacement-Kit
They also sell the center columns (which sometimes get lost, but are a necessary part of the light trap).
