I'm selling my wide-angle 65mm f4.5 lens for the Mamiya RB67 system. The lens is in excellent shape, both cosmetically and optically. It's the non-C version (serial 42436), same design as the C with the older coating, and performs beautifully. It comes with rear and front caps as well as a matching (shallow so no vignetting) lens hood.
Only selling it because I simply find I'm not using it enough to justify keeping it around; I'm asking $200 (plus shipping to Canada or US).
