There was no friction control on those old throttle/shift boxes.

you are correct, that feature was added on the next generation boxes that came out in the early 60s.  I did a little more research, and it looks like that white plastic knob on the newer engines with the little throttle arm (instead of the tiller arm) was an idle speed control, not a friction control like I thought it might have been…
