Hi kj2020,
thank you very much for your quick and detailed answer!
If I understand you right I could modify the setting lever jumper or replaced it with a 3230 two position one to avoid this ghost crown position and create a 1:1 3230 clone movement.
Do you know if the VSF VS3235 movent is the basic for a 1:1clone 3230 movement when replacing it with a two position setting jumper.
My idea is to build a 126040 no date from a VSF 126610 by modyfying the movement to a 1:1 3230 (if possible), dial and xtal.
