The envelope above appears to have travelled on the first airmail service from New Zealand to the USA aboard Captain Edwin Musick’s flying boat Samoan Clipper in January 1938 (originally scheduled for late December 1937, but delayed due to weather).
The sender is believed to be a New Zealand radio enthusiast living near Thames. Perhaps he was sending a radio reception report to CJCS, an AM broadcasting station in Stratford, Ontario, Canada. That would have been an impressive bit of “DXing” but certainly not impossible.
Known for being an avid stamp collector, it seems he asked the Canadian recipient to return the envelope for his collection. Indeed their correspondence may have been purely related to stamp collecting and not connected to radio at all.
Either way, it’s an envelope that reminds us just how important was the arrival of airmail service to New Zealand.
Sadly, Captain Musick and his crew aboard Samoan Clipper died on their next trip to New Zealand. Because of this tragedy, airmail service did not resume until 1940.
The radio station at Musick Point was conceived as a memorial to Captain Musick.
