VINTAGE MOTOROLA MODEL-55B1  TUBE RADIO  - No Power Cord - antenna does turn. much wear, numbers worn off dials.  as pictured. 

I rigged power with test leads.  It takes a few seconds to warm-up.  There was a persistent humming noise, and I could tune in a station or two  (bad reception here anyway).  The humming is present even when a station is tuned in.
