Watch out for mamiya/sekor m42s, many of which the entire aperture ring is overhanging. You can file it down like the Fujinons, just a lot more filing...
These are in fact the Mamiya Sekor SX series. The non SX series are fine, no filing needed.

That's what I thought until I picked up a M/S 135/2.8, which looks identical to the old SX version I had sold but this one doesn't say "SX" on it, just "Auto Mamiya/Sekor". The aperture ring still overhangs. Some of the Mamiya/Sekors also have a hard pin in the mount that needs to come out or it will get stuck on a Pentax...
