1924 Austin 20 Tourer
Photographed at the 2018 Bay to Birdwood Rally, West Beach, South Australia.
Introduced as the Austin 20 in 1919, the model was named the 20/4 in 1927 when a new model, the 20/6 was brought in. The 20/4 continued in production until 1930.
Powered by 3,610cc (220ci) In-Line 4, the Austin was a significant car in it's day, often being compared in the 1920's to the equivalent Rolls-Royce.
No slug either, a lightened 20/4 performed pretty much identically to a Bentley 3 Litre, and was successfully raced at venues of the time including Brooklands.
