503CW Problem- Maybe someone can help me with this issue. I took off the back, lens and autowinder on my 503 CW to replace the autowinder it with a manual crank. I put the lens back on but the manual winder is a different design than i had and I accidentally hit the mirror lockup before I got the autowinder back on So, I now have the lens attached with the leaf shutter closed, maybe it is half cocked ?, the mirror locked up and unable to put the auto winder back on because the lens has to be off to do that and I cannot advance the winder by hand Anyone here have actual experience with a situation like this?
