New Trav-Ler Style Radio Purchase!

I picked up a new Trav-Ler style radio at auction. I say "Trav-Ler style" because is it setup similar to a 1947 Trav-Ler Model 5020 I recently restored.  Trav-Ler radios were unique at the time as they were setup to work equally well on 120 Volts AC (Alternating) Household Line Current or DC Battery Power from A and B batteries. Their transformer-less design also allowed them to be powered from 120 Volts DC or Direct Line Current that was still available to households in areas were electric trolleys were still in use.  

Typically in this style radio, the left knob is volume, the right knob is tuning while the center knob allowed you to choose between Line Power-Off-Battery.

This radio could be a newer model of a portable Trav-Ler radio or another manufacturer's facsimile of it trying to cash in on the business. I won't know until I open it up. Hopefully the chassis will have tell-tale make and model information. Anyway, I can't wait to open this little beauty up and see what mysteries it conceals!
