I am not sure. There are two chokes. One is the field coil; that one is sure 3200 Ohms. But he asked about the #21, the filter choke.
The choke itself ... I asked the AI. The answer seems plausible.
The P/N is 3422-D.
AI answer:
The filter choke in a 1929 Philco Model 65 (part number 3422-D) typically has a resistance of approximately
200 to 230 Ohms.
I only found Parts list for 96 on Nostalgia, it is 3422 indeed. They are supposedly the same across this series of early 1929-1930 TRF consoles plus 111-112.
Also I found this on eBay:
Philco Filter Choke 3422-D (230 Ohms) Clean! (1929) fits many model Radio or Amp
Offered is the Philco Filter Choke type 3422-D. The choke is clean and in good condition with only a few blemishes here and there. It measures 227 ohms on the DMM. Used in Philco models 15, 40, 65, 76, 77, 87, 95, 96, 111, 112 and possibly others.

And no, it is not a misprint. Like I said, there are two chokes; yours shows the Field coil at 3200 Ohms which is correct, but we are looking for the filter choke.
