They had a website: www.bhp-sport.com but it doesn't work.
Now as I know the compnay has gone bust, but who got or owns the footage now?
I found a post from the Pistonheads forum:
Steve Rider was a director of BHP Sport ( Barrie Hinchcliffe Productions) he was removed from that post in the early 1990's as other production companies complained that BHP were winning all the contracts for Grandstand and there was a conflict of interest as Rider was also a presenter for the BBC.
I have been reading stories that Dukevideo got all of the footage, is it true?
