There are NO non standard Compurs in pre-WWII Schneider catalogues.
When Compur switched from the Dial-set to Rimset shutters they wanted to standardise the shutter sizes as it had been expensive making non standard sizes for some lenses.

today I got a Schneider Xenar 1:4.4/105 Serial 410093 (1931) in a rim set compur (a non self timed) in which is also unsymmetrical in both threads as my other prewar 105mm lenses.
So it seem in these days all 105mm lenses were standard front zero, back smaller for the mystry "0-nonzero" compur
Re: Thread sizes of old compur 0s and 1s?
I have a Weitwinkle Aristostigmat by Meyer Gorlitz that was in a dial compur with a smaller rear element and retaining ring than a standard #0. I have refit it into a later rimset compur of the same dimensions. These shutters have the same thickness as a standard #0. It looks like a cool lens - waiting for a suitable lens board. I measure the retaining ring size as 30mm x .5.
My belief is that these shutters would be listed in an OEM catalog from the period if such a thing exists.

here you find most specs of the more modern compur shutters:
