Skip,

If you ever get around to digging it out, see what the commercial part number 
is on the dynamotor.  I have a couple of units that I've been trying to ID 
for 15 or so years.  Made by Continental Electric.  About the size of a DM-33 or 
DY-8 but has small squirel cage blower on one end.  Has a 6-pin male Jones 
plug sticking out the side of the end-bell on the other end.  Continental's part 
number is DMDFX414T.  Dual outputs of around 400 and 210 VDC so I always 
assumed it was probably out of a transmitter-receiver.  No other nameplate on it.
