After I have submitted my previous question, I found another spacer in place in the Rodenstock shutter and the spacer is darker in color. I then think the spacer that came off is from the Super Angulon just because it is identical in color (bright bronze color) to the one that is in place with the Super Angulon. It seems that in my case the spacers manufactured by Rodenstock are different in color from that of Schneider. Will anyone please confirm my assumption? Is there any way to get assistanc from Schneider or Rodenstock on this regard? Larger format lenses are made in a way that they can be easily taken apart but why they are assembled with such a weak link. I agree that the quality of the lens with a misplaced spacer will be affected but is the deterioration of quality noticeable. If it does, does it mean I can test the lens by taking slides with all possible combinations of spacers and then identify the right choice?
