Hi folks,
Got one, made in 1920 maybe, where someone removed the speed controller - Possibly due to congealed grease issues.
Gather motor Swiss Made, but not a 'Thorens' as they stamped Thorens on metalwork.
Attach pictures as someone might have ideas.
Not a nice machine as horn made of cardboard, and with a crude wood cabinet with two front doors to control volume - Bit different from Quuq usuals though - Chris.
