This one offers a Gilbert American Flyer S gauge 30B 300-watt dual control transformer.

The transformer has been re-corded with a nice heavy, pliable cord.  Both volt meters work, as does the on/off switch.  Both circut breakers trip and reset properly when shorted, and the lamps illuminate accordingly.  The green lamp cover has been replaced with a reproduction.  Production date stamp on the base of the transformer indicates May of 1953  (EEC).

Voltage output readings look good:

Left Side -

Fixed Post - 19.8v
Variable at 0 - 4.5v
Variable at full throttle - 18.8v
Variable with dead-man's handle up - .016v

Right Side - 

Fixed Post - 19.9v
Variable at 0 - 4.v6
Variable at full throttle - 18.3v
Variable with dead-man's handle up - .01v
