I want to develope my negs in 4x5 tanks..I know about the Kodak rubber tanks and such. After waiting for some (3 ) to show on ebay ..bidding loosing ..bidding again postage more waiting ..may not get 3 at once..well you know. I thought there must be something in this world of numerous plastic disposable containers that would work for 4x5 tanks, so I am going to check several stores and sources for something that might fill the bill. Could you please tell mewhat are the inside dimensions of a 4x5 rubber kodak tank. Thanks again for your time and help.
