Remarks by Dave Fletcher: "The photo shows a radio installation in a Harvard wireless trainer during WW II. The particular aircraft was an NA-66 contract aircraft originally ordered for France but taken over by the British Purchasing Commission. It entered the RCAF on January 14, 1942 and served as a standard trainer at 39SFTS and 37SFTS before being converted to a wireless trainer on March 2, 1944. It was then assigned to No. 2 Wireless School at Calgary. It was reconverted to standard configuration postwar and ultimately sent to Turkey under Military Aid on November 9, 1957.

The equipment consists of a T1154 transmitter (lower) and an R1155 receiver (middle). The compass loop bearing indicator is on top of the receiver."
