Thanks for the welcome and the tips. Oddly enough my lense is stuck and won’t come off, but the shutter still functions fine.

My camera jammed. What should I do?
Even though I think the Hasselblad is the most dependable camera in the world, (ok, I'll admit it, I'm prejudiced), it is possible for it to jam. When a Hasselblad jams, it is usually due to a broken spring. If this happens to you, there is a way to unjam it.
The most likely time a Hasselblad will jam is when you fire the camera. (Naturally!) The blades in the lens will close, the mirror will flip up and the auxiliary shutters will open. So far, so good. But the shutter in the lens doesn't open for the exposure. You know something is wrong, but don't know what to do. Your first reaction is to try to wind the body. That's ok. So you try to wind the body, but it won't wind. Your second reaction would probably be to try to remove the lens. So you try to get the lens off the body, but it won't come off. So here you are with a jammed camera that you can't wind and the lens won't come off.
Here's what you should do:
Remove the magazine from the camera and place the camera on a firm, flat surface. If the back flaps are not open, gently push them open. If you look into the body from the back, you will see two screw heads towards the bottom of the front plate. The larger screw on the right is the screw that holds the front key cover in place. The smaller screw to the left of that one is actually not a screw at all; it is the slotted end of the front key shaft.
Hold the camera body firmly with one hand, and, with the other hand, insert a screwdriver into the slot of the front key shaft (the smaller one on the left). While you are holding the body with the other hand, turn the screwdriver clockwise. As you do this, the mirror should start to move down and the rear flaps should start to close. That's ok. Continue turning the screwdriver clockwise until it won't turn anymore. (Don't worry, you can't over wind the shaft.) At this point, have an assistant press the lens release button and try to remove the lens from the body.
Note: Do not use this procedure with any motorized body or any body with a focal plane shutter curtain!
Warning: Use extreme caution when following this procedure! If the screwdriver slips off the slotted end of the front key shaft, it can hit the rear element in your lens!
Once you have removed the lens from the body, you can determine which component is faulty, and send it in for repair.
