$55 shipped for the lot. The cost is for the film & mamiya back & shipping; I wouldn't try to peddle my home built camera but it is usable and makes nice results, so consider it a bonus.
2 pro-packs (5 rolls each) of Fuji RDP 100 daylight (provia)
1 pro-pack (5 rolls) RVP 100 (velvia).
2 other rolls of RVP 50 velvia.
