I should have said 1 gallon, instead of 1 liter. I meant 1 gallon in my mind. Sorry about that. I admit I might have jumped into a conclusion too fast. The Z131 publication still lists 1 gallon sized developer for small rotary processors. If Kodak has discontinued it the publication would have also been updated to exclude it. There is really nothing on Kodak web site that specifically says about the discontinuation of that package. I sure hope it is not. I don't believe it will any time soon. I think due to the explosive growing cost for shipment many retailers probably are not restocking chemicals as fast as they used to. That might have been the cause of shortage rather than being discontinued.
In my opinion if small package chemicals are no longer offered by Kodak there will be significantly fewer people shooting films. It has the effect of pushing people away toward digital. Thanks a lot, PE. You are truly the light house of photo chemicals in this forum. I look upon you for directions all the time here.
