I have a Calumet roll film holder Model C-2 (6x7) for sale. Very nice condition. I bought it a while back, but I don't think I ever used it. Not the first time that's happened! It's in great shape. They seem to go on ebay for around $65-75. I'll let it go for $60 plus shipping. Or make offer. I'm getting into wet plate collodion, so I need to free up some money. I can send a pic if you like. It looks great. I stand by what I sell. If you're not happy with anything I sell, send it back in same condition and I'll refund your money. Take a look at sdivot on ebay. My feedback is perfect.
