Does anybody use a Patterson Thermo tank 810 for processing 5x4 negs. I just got one at a market for $10.00 but its missing a bit from the LHS, this bit supports the tank and has a funnal for pouring chemical thur so allowing all processing to be completed in the light. I can make something from conduit but was wondering if there was some sort of seal to stop liquid leaking out during the pouring operation?

Thanks Shane
