Don't you love caution labels like this? This was an impulse buy last month when I bought this transmitter at the swap meet, I was first thinking I just bought a bunch of hard to find parts. Once I got it home though and took a close look at it, this transmitter looked original. So, I decided not to cannibalize it right then. Yes, it's been modified for ham use but nothing that can't easily be reversed. Other than the addition of a mica capacitor and alligator clip, those are the only non-original parts. There have been taps soldered onto one of the tank circuit coils, other than that, that's all I could find as far as modifications go.
I took a bunch of photos. I'm not exactly sure what I'm going to do with this radio but for now, I'm not going to take it apart. I'll try to track down the service manuals for it and see how difficult it would be to reverse the modifications. If anyone has a B-24 Liberator I could plug this in to, please don't hesitate to contact me! (Click on photos for larger size.)

I think this is the oscillator section. Center device is a 6200Hz crystal. Very interesting tube on the left, bounces something off the mirror on the rear cover.

Handwritten notes. No date.
Interior. The brown colored device is a mica capacitor
used for the conversion to amateur use.
