You are bidding for a video record of the long discarded 16mm film described below.   When the film  was made it provided a unique insight into its particular subject.  Over the last thirty years a number of ethusiasts realised that such films provided an untapped source of information on past techniques and methods At some time in the past it would have been rescued after being discarded as obsolete by the original owners .

Any money raised from the sale of this video will go towards offsetting the costs of more rescues. 

This DVD recorded during a showing of the short  film described.  DVD 1577

Far more detail than any leaflet  with advantage of movement

The trouble with electricity  is that a lot of pylons are in places that are not easy to get to.  One idea tried  was a hovercraft to take loads into awkward situation.  Rather oddly one plan was to drive a lorry on to the transporter  and then winch it.  . Although it had wheels most of the load was taken by the trapped air.  Movement was provided by a crawler of later a winch as conditions got worse.  Eventually it need one County with Boughton winch with another crawler in front to anchor  was required.  I suspect this did not continue development  as little more was heard of it. As such it is one of the Dustbin Films that is probably the last information on a project.

 With the EPS you got a power change for gears  but with electronic controls so you could not overrev the engine or charge up too soon.  It was part of a drive line specified for fuel economy. Useful if you are likely to drive one at some time. 

The theory was that if what you wanted to select agreed with what the computer accepted as possible you could make the change easily. If the computer thought your request was outside what it felt was acceptable depend how mush it was outside their range  it either  refused to make the change of sounded a buzzer or lit up a light  on the dashboard.   The aim was to save fuel by keeping in optimum ratios at all times.
