Graphic Rollfilm Adapter, RH-10-20 shell with 20 exposure lever wind insert. The RH 10-20 Shell accepts either an RH 10 or RH 20 insert. The 220 carriage may also work with 120 film (check for yourself), but if so, you'll have to remember that you're done shooting after 10 frames. Fits most any 4x5 camera having a Graflock ("Universal") back. Excellent shape, $75 plus shipping. Please reply privately.
