I've had to file down the mount of some J-9's to get them to fit on a Contax camera, and on adapters. I've also filed the bezel that fits over the mount before.
I use my J-9s, but on Digital these days. The best is a KMZ with an adapter, focuses across range on the M9.

What's the best way to figure out the "high point"? It can only be out by a fraction of a millimetre, but god only knows where.I've had to file down the mount of some J-9's to get them to fit on a Contax camera, and on adapters. I've also filed the bezel that fits over the mount before.
True- for the collar- I carefully placed on my beater Nikon S2 and could see where it hit the name place. Took the collar off, file- and repeat until it cleared. The bayonet mount itself- carefully position and inspect which hung up. I have a modified J-12, will get some pictures up- will be getting some time freed up next week.

Where on the lens would you potentially see flaked black paint?> It seems to loose all contrast at the drop of a hat, and I get way more duds with it than just about any other lens I own. But when it does well, it shines.
Just a suggestion: check the Black Paint used on internal glass elements that it has not flaked off. This happened to my 8.5cm F2 Sonnar. I used a Sharpie to blacken the exposed surfaces, solved the problem. I also use a very deep shade on it and the J-9.
But not this one-
On the Canon 7.

This is the black paint that is on the sides of the glass of the optical groups. Use a flashlight to check the inner elements. If you see white/mottled areas, the paint may have separated on is not doing it's job. Light coming in off-angle gets reflected onto the image.
