I found this today while Googling "duckworth building". Not what i was looking for (a building in Napier) but a wonderful site for anyone interested in Grand Prix; Past and present.
Grand Prix History This website has been in existence since May 22, 1997 and for much of that time it has been a little known secret tucked in a small corner of the WWW. Lovingly constructed, it is still one of the few F1 sites that attempts to go beyond mere statistics and describe what it was really like.
