[2] Norman Trescowthick had served with distinction in the Australian Flying Corps' famous 4th Squadron with Arthur H. Cobby during the First World War.
Although intended as an aircraft manufacturing and repair business based at Essendon Airport, by late 1929 it owned a De Havilland Gipsy Moth VH-UKV Diana that it used for charter flights.
The company became Australian agents for Desoutter aircraft, and one of these machines was used in the unsuccessful searches for ANA's missing Avro 618 Ten Southern Cloud over several months in 1931.
[3] In April 1933 the company began a regular passenger service between Melbourne and Launceston, Tasmania (sometimes via Flinders Island) using the Avro 618 Ten VH-UMG Tasman, formerly ANA's Southern Star.
However, following its failure to be awarded a contract for this leg of the Empire Air Mail Scheme early in 1934, it withdrew from the Tasmanian service in March of that year.
