There are a bunch of Wedge films around, just very difficult (so far impossible) to get.
" Buffum and Company" is about the 1977 season of Buffum racing made by British Leyland, one hour long.
"Road Racing's White Wave" film made by John Dugdale, US National publicity manager for Triumph. It is about the group 44 team.
"Rally Racing Fever" which is all about the 1976 racing season of John Buffum
"Success By Design" a film mentionned in Mike Cook's book 'Triumphs In America', which has a segment about the 1976 SCCA championship run of the Group 44 TR7 and the Huffaker Engineering TR7 driven by Lee Mueller.
If anyone has a lead on any of these I would love to hear about it.
There is also ton of footage of Canadian Rallies (Buffum rallied half the time in Canada)...how about the WRC race in Montreal in 1978 in think...there has got to be coverage by CBC, Canadian Broadcasting Corp.
There must also be a bunch of US coverages too. I have some grainy recordings with Tullius commentating on road races.
There are a couple of commercial rally films with bits of North American rally (wedge type)...
