I just a K3 off ebay – nice looking, very clean. 

I hand cranked it a few times, testing it, loading some dummy film.  Everything was OK.  I loaded my first 100 ft roll did a scratch test and everthing – still perfect.  Ran like a top – and after 75” feet, when I was winding the spring motor for another take, it broke.  I hear a snap, and the key just spins around.  Won’t wind anymore.  I removed the film, tossed the 25’ wasted.  How can I get this fixed now, or and I SOL?
