First flown on 26 June 1934, the Envoy prototype appeared at the SBAC trade show at Hendon just six days later. Behind it appears to be Hawker Hind G-ABMR, which is preserved today as "J9941" here at Hendon, but was a factory demonstrator.

Photo taken the day it departed Oakland for Wheeler Field, Hawaii on the first leg of a flight to Australia. It disappeared without trace. It is speculated that it overshot Hawaii after more favourable winds than forecast. The captain, renowned Australian pilot Charles Ulm, claimed the Envoy would float for days, so did not carry a lifeboat. He perished with his two crew.
