Just dug out an old C3 that belonged to my grandfather, and I have a few questions I couldn't find answers to online...
The shutter was in abysmal condition when I found it, but placing the shutter assembly in some lighter fluid helped quite a bit. Unfortunately, the shutter hangs partially open at speeds slower than 1/25th. It seems like the problem is not the shutter, but slackness in the metal ribbon/actuator/spring assembly. All other speeds fire well, but I have no way of checking for accuracy (I'm used to focal plane shutters).
Which brings me to my second question. It seems like there's a lot of leeway in how one mounts the slow-speed gear-train... theres a lot of play before tightening it down. Is there a way it's supposed to be set up? I installed it such that the slightest tension on the pull-rod already has the gear train engaged with the shutter-cock....
