When the curtain was first fixed it was noted by the repairer that it had previously been 'filled' with oil during a service which sounds very similar to your story. What can I expect if I send it to Leica Camera AG? Price? Time?
The total cost of the overhaul of my M4-P was about US$750 including a new winding mechanism (spare part cost US$250), which was about 5 years ago. I had sent the camera to Leica Japan and they were able to do the overhaul in Tokyo, so time was only 2 or 3 weeks.
