Heres a still from Channel 4 coverage of the 1989 Tour. The saddle looks like a turbo but has no branding.....maybe some sort of sponsorship deal with another company just like the non raleigh raleigh bikes perhaps???
I think they are all pictures of turbos.
St Laurent's backside is from the final timetrial I believe, the skinsuit looks very familiar!
"numerius" flickr stream is fantastic!
