I don't have any info on revisions so I'm unsure about the changes throughout the model's run. Mine doesn't have a phenolic board just blocks. I just assumed that since it was in a previous models cabinet that it would have had one of the first of the next models chassis.
The choke should be relatively easy to sort. Just have to calculate the proper inductor by using the known frequency and capacitance. As to why it's on a wooden form could be that it was cheaper to fabricate. Philco had a few bean counters and this was 1935, actually designed in '33 even worst money was tighter then.
I haven't really dug into the 201X but maybe I will in the near future.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
