I use this old thread, because I encounter a similar problem. The wind crank is stuck 180 degrees fturned from the docking point, the shutter is blocked. With or without spool installed, single or multi, locked-unlucked, all settings tried. Body was always okay. I use this camera for years, but I came by the user manual, and tried a sequency for replacing the lens that was in there and that I never used:
'1. If the film wind crank is not kept positioned diagonally upward, (the same angle as the crank housing position), the cocking lever (17) cannot be connected'
(I never flipped the crank upwards before..., and now I did, it is stucked...)
Any help on how to unblock, would be realy appreciate
