Good morning Wiz.
Thank you for the information, very helpful!
Unfortunately, I am struggling to find a suitable motor - I don't want something quick, just with more torque and modern (safe) wiring. The closest I have come is a unit from the YDK brand, like this: https://coulingsewingmachines.co.uk/sewing-machine-motor-foot-control-kit-ydk-with-belt-and-bracket/
I have looked at some Chinese options from AliExpress and Temu but am unclear which ones are suitable.
Finances are tight, so keeping the costs down is paramount.
