Congrats on your find, Dave!
The BC221, etc, can also be used as a very stable VFO, to drive a xmtr.

Interesting. Most BC-221 were
originally battery powered and later converted with
makeshift AC power supplies. Your's obviously was AC powered
from the get-go. There were over 25 different different
models made by a slew of different manufacturers for use
during WW II. Few of them had a modulator.
I have found the BC-221 to be a very useful while nostolgic
piece of test equipment. As long as you have an idea as to
roughly what frequency you are beating the signal agsinst
(generally not a problem), it can be used to accurately tune
transmitters and receivers to a specific frequency. It can
even be used to align IF frequencies eliminating the need
for a frequency counter and RF signal generator.
Thanks for sharing.

</div>This unusual BC-221 followed me home from a
hamfest a few years ago. The
guy practically begged me to take it.
I just got it out of storage a few days ago.
I have never seen one like this and don't find any model
numbers on it.
I did have it on the bench and it works.
Attached are some pictures.
