Permit me Dale. I restored the first Norton P11A (750cc Atlas engine) in the UK back in 1986. It was re-imported from the USA. None were sold in the UK as they were built for desert racing. It had the Reynolds 531 frame designed for the Matchless G85CS. (I had a works prototype G85CS and an AJS 18TCS Typhoon too. Plus a 1967 G80CS so accurate that Don Morley bought it.) To complete the restoration I had to beg Reynolds for a frame sticker. They did send me one. These bikes were special because of the big torquey motor in the lightweight 531 frame. It really hauled ass away from the traffic lights and would leave Jap bikes dead for the first hundred yards. I am surprised I am still alive to tell the tales.
Sorry, totally off topic apart from the tubes.. I was big into motorcycles
until my daughter was born then I lost it. I had in the meantime been
commuting to work on cycles and the bug went from motorized 2 wheelers to my
own 750cc's. I worked at Camberwell College of Art as metalwork technician.
The first bike I bought was 2 speed Sunbeam from 1927 then I found a
Gillott.
