This is a CB103 Polaroid back with a Graflex XL mounting plate on it. The rollers are clean and move freely. This does not include a dark slide. The mounting plate on this could be changed out for other mounting plates to fit a Polaroid 600SE, Mamiya Universal, RB67, etc. Could also be used for a conversion ie 110a.

Looking to get $50 (together) + S/H from Ohio. If that sounds steep, message me and make me an offer.
