I'm going to sell my old Beseler. There was an accessory packed with the enlarger, but I can't remember what it is for. Could someone please check out my photo and tell me what it is? Maybe it's some sort of wall mount for the paper tray or something? But why would I need this if my enlarger is mounted on a board? I'm sure it's easier to figure out than I'm making it, I just can't remember! It's the white tray with a wall mount on the left. Thanks! beseler2 on Flickr - Photo Sharing!
