Hello- First post here. I finally got ahold of my dad's M2R that he's had for decades. I had the opportunity to shoot with this one about 18 years ago, but unfortunately it hasn't been used since. As you would suspect it doesn't want to run right after the long wait. From reading other posts here I have concluded that the rear curtain is stuck as a result of the self timer. There is no film loaded. The first shutter and winder work fine. When the shutter is pressed, there is a click and only when it's released does the first shutter slide out of the way. The self timer is about 20% engaged. It will not wind further and there is spring resistance when it's pushed back to it's resting position. Any suggestions before I send it off? Thanks!
