I'd be interested in the parts as obviously I have the wrong one. If the part lends itself to 3d modelling that can happen too. We can correspond backchannel (Fokker too). I suppose a first step is to determine if there is a metal insert in the bakelite. Can you see if there is by looking at the back of the knob? I just noticed you're just on the other side of Robert Louis Stevenson state park from me.
