Hi Jody

I recently helped a friend, who is restoring a Green Welte Upright
Reproducing Piano, with the connections for the motor and the
control/starting system.  We worked out how to connect the system
to enable the motor to start and run reliably without overheating,
but he insists that there must be a way to have the motor run at two
different speeds, as this was normal for this type of player.  I have
attached a photo of the motor and the control components which you may
be able to make available to any interested  readers that may be able
to help me with my problem.

There is one other mercury switch in the piano that switches the motor
on and off, but apart from that and the components in the photos, there
seems to be nothing that could be used to change the speed of the motor.

Have any readers come across this system before, and if so, is it a
single or two speed system.

Thanks in advance to anybody that may be able to help here.
