G-AUBZ had a remarkably long career for an aircraft of its era. Registered in 1921, it was around long enough to became VH-UBZ. It was initially owned by legendary pilot Ray Parer, then went to Qantas and on to Matthews Aviation at Essendon. It remained in use into the late 1930s before being struck off the register in 1940, Photo from: National Library of Australia

Dayton-Wright built DH-4 32517 has been restored by the non-profit Friends of Jenny organization. Their aim is to fly the aircraft again after re-building the Liberty engine.

Originally with Qantas as G-AUBZ. Sold to Matthews Aviation in December 1927. Was still marked G-AUBZ at the start of 1930 despite a CAB directive to change it to VH-UBZ. That happened in March. At the time the aircraft had open cockpits (five) and was named "The Lachlan". Sold to Pioneer Aviation Services in 1931. At some stage the rear cockpits were replaced by an enclosed cabin. At least five (excited!) passengers are visible in this photo. -UBZ was finally struck off the register in 1940.

The British DH.4 was one of the best light bombers of WWI. A huge number were built in the USA in 1918. This airframe was rebuilt for the US Post Office by Boeing in 1923. It was later owned by movie stunt pilot Paul Mantz.

The DH-4 was a 1917 RAF day bomber. Examples sank German submarines and shot down Zeppelins at up to 16000 ft. 4,587 were US-built, mainly with Liberty engines, for service with the Army Air Service in Europe. Postwar the DH-4 remained in US military service until 1929. No.166 was one of over 100 upgraded DH-4Bs used postwar on transcontinental airmail routes by the USPO. 400 lbs of mail was carried in a compartment replacing the forward cockpit. From Douglas A/c.

G-AUCM was one of the first Australian civil aircraft and was registered in 1921 after service with the Royal Air Force as F2691. It is not known who owned it when it was photographed at Albury but by the end of 1927 it was in Papua New Guinea. G-AUCM was withdrawn from use in 1930 without adopting the VH- prefix (it would have been VH-UCM). Alexandra Park still exists in Albury and is about a kilometre from today's Albury Airport. The photo was found at a garage sale in Albury and the photographer is not known. The details were pencilled on the back.
