Above: previously shown sample of this mystery turntable.
Clearly there are two different platter systems. and I presume the chassis size to be smaller on the 'non-broadcast' unit.
My thought, in order to authenticate this find, -- one would look for documentation (any kind) to support its existence. Corporate authorized sale advertisements, for instance. This turntable is too early, we presume, to be included in the EMT-Courier bulletin that was first published in the early sixties.
Magazine articles (any language) and advertisements.
It does look like something that EMT could have built, had they intended to. But as a changer...? Would they do that?
I wonder about the pivot to spindle distance on that sample. Does it duplicate the EMT 929 or Ortofon RMA 229 mounting distance?
