I was watching that video (again) and about 8:40 in it shows Dan Gurney go by and it looks like he's got a "K&B Aurora" sponsorship logo on his McLaren-Ford.
Terrible picture I know, but if you watch the actual video, it looks clearer.
I didn't know that brand did actual car sponsoring. I knew about Russkit and of course Cox, but not Aurora...
