Who makes the movements for Sligh?

Being modern reproductions, I assume the movements in Sligh clocks are outsourced to Hermle or Kieninger in Germany.

I'm in the UK so we don't see too many of these US clocks over here.

Does anyone know the manufacturer's model fitted to Sligh 3T clock Model 0840-1-N please?

Sligh give it the reference 500-0014 but I suspect that is their own cross reference and that the makers have their own.

Thanks in advance (from the UK)
