This was also released in Australia as The Tomy AFX F9724 Racing Turbo version. Below are some details from Google, although I edited the details, because it said the Australian F9824 release was a rumor.
This car is also shown in the 2008 Australian catalog with both the SG+ version as F9824 and the Racing Turbo version as F9724. I have included pictures showing the pages from that catalog.
F9824 SG+ Stocker Imperial #62 very rare from Australia. The Tomy AFX F9724 Racing Turbo Version (often referenced in association with stock numbers like F9824 SG+ version or regional variants) Imperial Stocker #62 is a rare HO scale slot car originally issued as part of the Big D Stocker Challenge Set (#9950) and later distributed in limited regional markets like Australia.
The Set: This car was natively included as part of the rare AFX Big D Stocker Challenge Race Set (#9950) released in 1997. It was paired alongside the "Gasoline Stocker #14". Design & Appearance: It is a purple and white stock car sporting Car #62 and black wheels. The Chassis: The original Big D Stocker Challenge version body sits on a Racing Turbo (RT) slot car chassis, which was highly popular for its reliable magnet-based downforce during that era of HO scale slot racing. Finding an intact, standalone version of the #62 Imperial Stocker is considered a major milestone for vintage HO scale slot car collectors today.
It is too bad I did not get the original package with it when I bought this used from Australia. This car will be a nice looking one of a kind addition to your collection. This will be well packed to hopefully avoid any possible damage.
