Shown here, on the cover of QST for September 1939, is the portable/mobile ten-meter station of Harold Bowen, W1DQ. According to the magazine, at the microphone is his unnamed assistant operator.

The details of his station aren’t given, but since the unit on the right has a dial, it’s undoubtedly the receiver, with the transmitter being in the middle.  The unit on the left is unmistakably a dynamotor power supply.

According to this family history, Bowen was a World War 1 veteran, having been in charge of communications on the U.S.S. DuPont.  He died in 1973, according to this obituary.
