I may try and fix it myself by putting all the bearings back in but I'm not 100% sure how the plunger goes back in. If anyone has a pic of a working unit I would love to see it. I'm wondering if the little cap that is on the plunger (for lack of better word) that holds the bearings in, needs to be glued on or something. I'd love to have it working 100% again because it is one hell of a find. I have about 5 or 6 film holders, I even have the Graflex multi film holder that holds like a 10 pack of film. I have the original flash along with the original Graflex Vulcanoid case. The guy that had it was an engineer and very meticulous. Perhaps they should have called him when they were designing the rangefinder cam assembly because it sounds as if this happens a lot to folks.
