I just bought an untested for parts 500EL off ebay (yeah, i know, took a risk of needing a service) and it’s jammed. The mirror’s up, the barn doors are open, and the shutter winding peg is in the fired state. I tried manually cocking it from the back, but that didn’t do anything. It only rotates a few degrees before feeling jammed up

Fresh 9v battery, when I press the shutter button the feeler peg for the darkslide springs out of the body and retracts when I release it.

Any potentially easy fixes I can try before I send it off to have it CLA’d?
