In the late 50s David McKay was sponsored by Victa Consolidated Industries with an F1 Cooper. 
Jim Roberts, Foreman at Victa was the mechanic on the car and photos of the build of this car have come to light with Jim being featured in some of them at the Cooper factory in the UK assembling the new car before it was exported to Australia. Thank you to Bryan Cunneen for allowng me to scan these rare pics for  'Aussie Road Racing.'

 I purchased a Cooper from the Sternbergs in Burnie in the mid 60s that had previously been purchased from Bib Stillwell and was reputed to have the 2 litre climax from the Victa Industries car after I purchased it I removed  the engine and gearbox and used it in a sports racing car I had built this  car was eventually sold to Ken Hastings in Victoria and renamed the Atom  the car came back to Tasmania without the Climax motor.  Cheers Bob Wright

Feedback on this car from a viewer in Tasmania - Bob Wright ..thanks Bob.
Bryan Thomson from Shepparton in Victoria ran the car in the early 1960s. Bryan has supplied us with photos of the car with the Supercharger fitted. Bryan says:

Ex Victa  F2 14 59 T51
"Really appreciate the story of the build - some photos attached showing the supercharger installation . The comment of the original engine going to Tas. is interesting as I purchased the car from Stillwell less engine , and then purchased the 2.4 FPF ex Austin Miller .

"Pics at Tarrawingee 1962-63 season. New lap record . Car was dismantled in late 1963 , and all running gear built into new Elfin Mallala . Regards Bryan .​"

Thanks Bryan for the photos and information ... Brian D.
