I believe this is what Chris Probst uses on the 40mm Kowa to convert it to a 32mm Kowa. Not 100% sure.
In very good condition, threads on the rear are machined down
$150 ship (due to cost of modification).
Also works on a 24mm FD L or something but don't damage your lens! I broke a 20mm f3.5 this way.
