Thanks! I just wondered if it might have been a U.K. make as I know that several of our turntable manufacturers sold quite heavily into the North American market at that time (BSR and Garrard particularly).
The part I could see didn't look like one of "ours" but I wasn't certain. Still don't recognize it now I can see all of it.
Ragnar,
In the U.K. 4-speed changer decks were common at this time throughout a large range of equipment, from the cheapest portable Dansettes right up to the fancy "radiograms" similar to this one. Of course, the 16 r.p.m. setting almost never got used!
