How do you keep your benchrest from jumping around on the bench?

I checked that link out. The knobs, that are being discussed in this thread, are not shown at MC. The knobs he's referring to are the 2 that are on the screws that tighten on the center post and the capstan wheel.

Keeeerecct!!!

If you are looking for exact OM type then would recommend contacting the OM. If not there are hundreds of sources for Knobs out there. Here are a few more. I am sure that you can find one that would be acceptable to you.

Do a Google search on Industrial Knobs, I hope that you find what you are looking for. I doubt very much that the OM produces their own. They are most likely purchasing an already made handle knob and then attaching a stud (threaded at each end) to it to produce the complete handle assembly.
Good luck in your search.
