Hi R Radbill, 

Wow, a 31 Lincoln!  Model K, KA, KB?  V8 or V12?  A really cool car (I am prejudiced I have a pathological love for Fords, Mercs and Lincolns).  If the B Supply was by batteries, they would be in a box either under the back seat or under / through the floorboards.  Vibrator or Dynamotor supply would be in the same area (?).  I have read through several installation instructions for radios of this type and have not seen anywhere where it was recommended to installed a battery box, vibrator or Dynamotor in the engine compartment. This should be a rather quiet car so at least the radio can be heard.

This is a TRF set, should be rather easy to restore.  A transformer with 120V primary (used as the secondary) and 12V center tapped secondary (used as primary) a, full wave solid state rectifier and vibrator can be used to build an appropriate "B" supply using the schematics of later radios.
