I recently acquired a Kodak Chevron (with a lens code of 1953.) Although the Synchro Rapid 800 shutter fires at all speeds, there a intermittent lag between when the shutter release is pressed and when the shutter fires. Also, the shutter speeds seem somewhat slow (although I haven't been able to test it as yet.) Before incurring the cost of an expensive overhaul, I thought that I would simply give the shutter naphtha flush. However, before I do this I want to remove the front and rear lens assemblies. Now the front one unscrews very easily, but its not apparent to me just how the rear assembly might be removed through the film cavity. Does any know if this rear assembly can be removed from this vantage, or am I faced with a major camera disassembly project? Pete Lerro PS: just an aside - I also own a Kodak Tourist (with a lens code of 1948)and it has the same type of Synchro Rapid 800 shutter. Now I was aware the Chevron shutters do not age very well, but I'm somewhat puzzled since the Tourist's shutter, although five years older, does not exhibit any of the problems which I experience with the Chevron's shutter. (However, here too, I haven't been able to test the Tourist as yet.) PPS: Does anybody out there know where one can acquire a used Calumet Shutter tester?
