Synchro-Compur M-X are the first version of these shutter, something in between previous Compur Rapid and the next Synchro-Compur which already have V mode that means selftimer inside the shutter.titrisol wrote: ↑Sat Jan 14, 2023 8:24 pmIf it has the Synchro-Compur it must have the M-X switch for flash
Some of those have a V next to M and X and that is the self timer
I guess the number of shutter variations are much larger than reported
Mine is a W serial number and has a Compur-Rapid (1-500) and only X flash sync
What I see now that I look at yours, is that the cable release is in the opposite side (180 degrees).
Mine has it where the MX switch is.
Ikoflex IIa has this first version of M-X and have no selftimer, Rolleiflex 3.5A has the same shutter and they added the self-timer mechanism next to the viewing lens.
