A pair of 'Longbridge' 


1. The thin metal bar type arms

2. The screws around the rear pane

3. The rear pane is fixed and the front moves - very impractical for hand signals!

4. The angle of the rear pane is forward leaning and not parallel to the leading edge

This is from the original 100-Six Service Manual.

The angle of the perspex is  forward sloping like the later screens even though this is an early screen. In addition there are screws around the exterior of the frame which is not the case on the 'Longbridge' frames

Peter Svilans believes this was a very early variation which went out on the first 50 or so cars. A similar screen can be seen on photos of UOC 741, which was an early press demonstrator before becoming a works Rally car.

This photo shows the star shaped  nuts that secure the front of the sidescreen and the single eared wingnut that attaches the rear bar

Here is another example clearly showing the shape and design of the rear bar

A third type of Sidescreen
An 'Abingdon' Sidescreen


1. Flat bar attachments

2. No screws in the frame

3. Perspex is parallel to the front edge of the frame

4. The rear panel moves, the front is fixed
The two eared wing nut can be seen on the front attaching bar

This was also used for the rear attachment as well.

Note that this type of sidescreen was  introduced during the production of the 'Longbridge ' type BN4s  from
