Picked up a small table model DeWald radio the other day. It has no other info on it other than the DeWald decal on the front. Fairly early, 2 band, 2 knob (plus band select knob in back), small round dial.. probably around 1933-35. I looked for a match on the tube line-up in the chassis, but had no luck. Came close on a model 402, but no dice. Tube line-up is...6D6-6C6-43-25Z5 and 185R4 ballast tube. Any help is appreciated.

Verify if model 506-R is correct.

Bingo! That's it....Probably the only one I didn't check...
