Hi Mickey
As a few have said looks like a pretty straight forward superhet. The mixer tube is a little odd 6F7. It's not a very popular one. Covers two bands AM and the old police band with an IF of 465KC. Back in the 1930's the bc band ended at 1500KC. Now it up to 1700KC or so this means that it will cover the new bc band and then some. There is the 160 meter amateur band which covers from 1700KC to 2000KC or so At 2500KC there's WWV the nation bureau of standards time,frequency,and propagation reports.
Here the service info:

Enjoy!

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!
