Looks like it could be a fun radio to put on 3615KHz with a suitable crystal. Should do about 15 Watts output.

Re: Aircraft Transmitter AVT-15
I think you will need a large old style crystal in that co/pa circuit. Modern, small metal can types would not last due to stress caused by the sheer power requirements of the 6L6 osc/pa. I have no experience of this, just what I read decades ago.
The old style 10X should be ok. Take them apart and spend hours grinding to change the frequency hf a few khz! Yes, I did that in the 1960s! Rob
