I should have included this earlier, the thread from slashdot, some guy made a list of all the different places one can get custom made parts.
I am thinking the possibility of converting a spotmatic into an RF, with custom made chassis and everything. Doubt I will ever make this thing, but it is nice to dream. I have heard some guy in Hong Kong had modified a spotmatic to have a Rollei lens mount and Fuji ST901 prism! Apprantly the craftsman had made a few in the early 80s.
