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.

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. http://n7rk.com/radiostuff9/bc221unusual.jpg http://n7rk.com/radiostuff9/bc221unusual2.jpg http://n7rk.com/radiostuff9/bc221unusual3.jpg http://n7rk.com/radiostuff9/bc221unusual4.jpg http://n7rk.com/radiostuff9/bc221unusual6.jpg http://n7rk.com/radiostuff9/bc221unusual7.jpg Anyone seen one like this?
