Here's a question for the Beseler people. I somehow ended up with a 2-1/4 X 3-1/4 negative carrier that is 8-1/4 inces in diameter. The markings on this are 2434RN. I'm thinking this is a carrier for the older Beseler 45 series but when I look at their web site the same size carrier has a part number 8314. I want to sell this item, but hesitate to start until I am sure what it is. Can anyone help on this?
