Bolex motor mounting screws

[Olaf Trevilla]

I recently a purchased a Tobin TCS TTL and noticed my mounting screws are way different than all the ones I’ve seen, my screws are sunken in and I have to use a flat head to screw them in where as all the other TCS TTL I’ve seen having little knobs that you can just twist with your fingers. Does anyone know what kind of screws/knobs these are and if I can replace them or even find them?

Looking at some instructions online, https://www.urbanskifilm.com/TCS_Public_PDF/TTL.pdf I'd say yours just has (or rather hasn't) missing knobs. I think the knobs just engage with the screw slots to make them simpler to turn. They probably hold on with a rubber ring and yours have just fallen out. If I'm right, a flat screwdriver will be fine, just not too tight.
