Regulations regarding specials

[andrew34ruby]

PS In part answer to the original post question I believe (and may be proved wrong) that construction and use regulations for cars came in after the war.  I think that as long as a car meets the regulations of the day it is acceptable. An exception is reflectors that was a requirement imposed retrospectively possibly during wartime?

I think there are various exceptions as well as reflectors.

I'm thinking that all cars must now have...

Reflectors
A rear view mirror
A windscreen wiper
Screen washers

and all after some date in late thirties have to have brake lights and indicators.
