1935 Philco 89B schematic?
#3

Thanks, Ron. Yes, all the 89 sets I found had the drum type dials and covered the wrong range for SW. That's what confused me. The cabinet DOES look very similar, at least to my eyes, so I can understand if the seller misunderstood which set he had. I wonder if he looked at the label inside ? (if one is still there)
1935 89B (which came out in June of 1934)...

66B (which came out later in Fall of 1934)

In fact the production numbers listed for the 66B include the 39B and 89B ! so I suppose the cabinets were the same, although the dial escutcheons do look a little different if you really look closely, and the drilling for the control shafts is slightly different.
