[Healeys] Proof needed

[Pieter and Linda]

I am taking my car to the local TUV station in Germany tomorrow to try  
to get the Dennis Welch rear brake conversion approved. I have just  
been told that it would help if I could take some proof that rear disc  
brakes were fitted "in period", even if only to the works cars as  
these also carried registration in the UK and therefore in europe.  
Most of my Healey books are still back in storage in OZ. If anybody  
has the time to scan a page or two out of a book or can send me a link  
to some "proof" it would be greatly appreciated.
thanks
Pieter
