I seem to have somehow jammed the body of my Hasselblad 500 C/M. I understand the common lens jam problem and that both body and lens need to be in the same cocked or uncocked state. If I cock the body without lens or back attached, I can release the shutter to uncock it, but then cannot wind it on to recock it. Also if I cock the body then try to attach the cocked lens, I cannot attach the lens. Is the body damaged or am I missing something?
