It's the first 'Kudensay' (Couldn't say!) which was written off by Neil Montcrieff in the 1950 Johore GP (pictured) in Singapore, then rebuilt as Kudensay 2 For Roy Kendall in 1951. The Fiat chassis carried a Ford V8 ........! As Montcreiff and Kendall were both Qantas engineers based in Singapore, I assume they were the builders.
