Thanks for the link GTR Magic.
Graham Moore's VK was the HDT 'T' car from Bathurst 85 that Allan Moffat tested here:

Presumably it was the car Brock & Perkins had debuted at the Wellington 500 in January.
HDT built a batch of VKs in mid 85 for the privateer market. Gerald Kay and Alf Grant were both buyers. The Ray Smith Auckland Coin & Bullion car may have been another.
