Anybody know where or if I can obtain new (or not at all fatigued) main drive springs for older synchro compur shutters (specifically size 0, but I'm also interested in others)?

I hope my terminology is correct - I'm looking for the spring that attaches to the cocking-arm.

I've been doing CLAs on my old shutters, and I've found that some of my S-Compurs clean up very nicely, and that once I de-grease and re-lube them, I can adjust the little tension spring on the speeds escapement as well as the position of the speeds escapement in order to get a nice close-to-accurate one-second speed. But on others, I've moved the tension spring and escapement position to their extremes, yet the one-second remains slow. I can only attribute this to a far-too-fatigued main-drive spring; hence, my search for new or like-new ones...

Thanks...

I have a Compur shutter that has a broken pin that connects to the shutter speed dial. I am not sure what size it is but I can send you a pic of the front plate if you are interested. Let me know your email and I will send it to you.
