Hi and welcome to the Phorum,
The primary of the coil is not very critical in terms of the # of turns. It's just there to inductively couple the rf signal from your antenna to the 2ndry of the coil. Generally they are don't have a lot of turns so not too hard to rewind. On the 1937 and 38 model they are hard to get at because of the design of the chassis. The 2ndry is as it is part of a tuned circuit comprised of it and the tuning capacitor.
To be more accurate that coil has two windings w/four leads.
GL w/ your project & Happy New Year!

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!
