That looks like a double conversion IF. The IF cans are 85 kHz from the LF Command Receiver.
I assume the extra can wedged in there is 915 kHz and one tube is the converter 915:85
I thought of doing this, some years back, and then thought, nah, live with it as is.
One trivia type item: the Squires Sanders SS-IBS and SS-1R have their IF at 1000 kHz.
But they get the AM selectivity only thru LC’s at this frequency. The coils in the S.S. receiver
are much higher Q than the ones in the BC-348, which are Q about 100+.
