I measure 32.45mm on the lens and 31.02mm on counterring.
Is it now M32 x.75 or M32.5 x .75?

someone confirmed: M32.5 X.75
Makes sense is universal size also used by Schneider for some of their enlarging lenses.

These eskofot lenses are very well known and eskofot is the marketing name, rather than the actual maker. There are many previous threads with data if you use the correct name EskoFot (German rather than French/English!).

IMPORTANT UPDATE:
Eskofot Ultragon 9/150
M32.2 x 0.5 NOT 0.75
i tested it on both adapters. one is obviously wrong.
made a mistake when measuring with a pitch-size-tool. no wonder if doing the first time.
here i found the confirmation: i have also this G-Claron and Eskofot have the same thread.

The 150mm G-Claron has an M32.5/0.5 thread that I can adapt using the Schneider 0 to Leica adapter.
G-Claron-Data from datasheet-library. it is offline but i posted link to archive.org where it can be recovered in Largeformat Photography Group in FB. Must check again where these data are. Maybe opening a new thread anD uploading a zip. but it maybe be really too large with 163mb.
