My only cloth shutter curtained camera left is the Standard Leica.
also, look for bubbling of the rubber on the side facing the lens. I tried burning a curtain a while back and it would smoke and the texture would go all bubble-like before it burned. I'm not sure all burnt shutters will show that though.
good luck...
Check both curtains, Raid. Advance the shutter and check. Then release and check again. It should be somewhere.
If the sun was strong, it might be a pinhole, it should be! If it were a big hole, the spot would have been much larger. You may need to point the camera at a very bright and steady source like a halogen ceiling light, and move it around a bit while looking at it from different angles.
Hi Raid,
Take a second look at your ruined film and tranfer the position of the star on the frame window, to indicate you where to precisely look at.
Have you considered a processing error, possibly a spec of dust in the processors system?
