Mike; Peter;
I think that the governor on the phonograph/gramophone motor in the HMV actuates a brake rather then changing the gear radio, as the balls fly out it pulls a disk against a pad of some sort like felt or cork, and it slows the speed slightly. Was the phonograph made by Gerrard, it looks like a Gerrard tone arm?
With regards to portable record players with a spring motor, I can remember hearing that they made them in India right into the 1970s, if not later, they too may have been HMV copies, as a lot of products made in India were licensed copies of older British ones.
