I don't print larger than 8x10 anymore since I started contact printing. I have 4 of these drums that I used primarily for processing color paper. I've also used it for both RC and FB B&W paper with no issues. No use for them anymore. As you know several in our community constructed inserts for using this drum with film of various sizes. It's a very versatile drum. I have 4 of these for sale, all in great condition. I'm looking to get $175 US each + Paypal fees + shipping. PM or email (luigi@luigipasto.com) for questions, etc.
