Lionel Postwar ZW Transformer 275 Watt Tested and WORKING

A Used Lionel ZW "Trainmaster" Transformer from the early 1950's postwar era.  Has been tested with voltmeter and all four circuits work.  They were a bit slow to come on at first, had to move the handles back and forth a few seconds first.  Possibly needs a cleaning service.  Whistle and direction levers also work.  Working lights.  Handles and slide levers spin nicely.  Power posts on back are rust free.  Baseplate has some rust.    Power cable in good shape, no damage.  Case has a large crack on upper shell, and a hole on lower shell (see images).  Missing 'Lionel' top plate.
