> I'd love to find the same orginal ones (hem hem), but if not possible, I need to find the same kind. The shaft is very thin. They go with the orginal Davies knobs mounted on the original serge, with very small holes.

> If you have an idea where I could get these or ask, I'll start checking which values exactly I need for all the panels (I guess there are not all 100k as the ref numbers change).>
