   You are right-  the battery would have been of the mid-40's vintage. It   
   was a fairly large dry cell (6"x9"x2") or thereabouts) ostensibly used   
   for an electric fence power supply (problem here would be short life -so   
   it could have been intended for something else-). The ignition coil was   
   "OLD" -well potted in a wood box, "trembler coil" type.   
   Did I risk fibrillation? -apparently not- some insulation as well as   
   being bypassed by the battery itself -limited current and let-go wasn't   
   a problem.
