May I draw my fellow TNF'ers attention to this channel. It has a number of little vignettes on it, as well as some seriously vintage films that are so bad they are good!
However they have a series called "Look at Life" which was filmed in the late 50's through to the late 60's and today's one that I (re)caught was entitled "Speed Kings" and has some fascinating paddock and racing footage in it with appearances from Stirling , Tony Brooks and Jack Brabham.
It also covers the "Racing School" at Brands Hatch and has some lovely sequences of people following Ian Burgess around the track and being "judged" by people sitting in a box on the start finish straight as to whether they'd make the cut.
I wish I could remember the name of the young lady who's mother was "appalled" she'd attended the school, I have to say I did wonder if she carried on at all!
Well worth a look.
There was another short on the other day as well showing the fitting of the Laycock overdrive to the MGB and how it gave a 16% improvement in consumption so for every 5 gallons you got a 6th one free.
