    The one being auctioned is very close to

	http://www.telegraphsofeurope.net/page142.html

That model could be equipped for either weight drive, electric
motor drive, or both.  The one being auctioned seems to be
equipped for electric drive only, although notice that the table
has the pivot for the winding pedal and the mechanism has the
drum and gearing for the 60Kg (!)  weight.

    Here's the weight-only variant (no motor installed):

Note the heavy chain going down through the unit. That
connects to the weight.  There's a pedal under the table
for winding the thing.

    The machines with the tall governor tower are
German machines.  The earlier American and British variants of
the Hughes machines used a different, flatter governor.
(The Phelps printing telegraph, from 1885, used an
electrical governor that worked by cutting a resistor in and
out of the motor power circuit, just like governed Teletype
motors through WWII.)
