[R-390] Knobs and screws

[quartz55]

I broke the tabs on one of my large tuning knobs, so it's useless now.  I see one of the clamps I have also has a slotted machine screw instead of the Bristow screw, don't even know if the nut is right because it's a 6 sided nut, the clamp is good.  So, if anyone has a large knob and the Bristow screw/nut set for the clamp, I'd appreciate it, gladly pay for it.
