I've just landed a Graflex Century Graphic with a roll film back. It's in excellent condition except the bellows are bit worn and have been repaired in the past. They're light-tight at the moment though. Antybody out there got any experience/tips with using the camera? In particular, is there any way I can protect the bellows from further deterioration as I reckon that to replace them would cost more then the camera is worth (I payed £80 for it on ebay!).
