That's because the originals were put together in small batches and the frames were hand made by Brian Curtis who's work (as you correctly noted) is magnificent.
Thanks- knowledge is but a touch of the key pad
I now see it was also the maganese that also has a brilliance about the work produced.
The story goes on the above mentioned bike,that the owner got three of the four that came into the Albany Port south of Western Australia,not sure on the timing though..
Something I will have too ask the owner at a latter date, as he was busy kicking over another of his Yamaha's.

http://www.curtisbikes.co.uk/info.htmlQuote:Here at Curtis we build our frames from a type of tube called T45. T45 is a combination of Carbon, Manganese and Steel and is one of the strongest and highest quality tubes available. To top it off it's made in England! T45 is used a lot in the aerospace and motorsport industries because of it's superior strength to weight ratio over other steel tubing. T45 was used to construct the chassis on Richard Nobles Thrust 2 land speed record car. T45 is not easily available abroad which is why all imported steel frames are made from American or Taiwanese 4130 Chromoly.
Chromoly tubing also requires heat treating after any welding or brazing, where T45 does not require any heat treatment whatsoever. T45 is simply a stronger and higher quality tube than Chromoly. We have been using and brazing T45 tubing since the 1970s, and it is due to our choice of tubing, along with our reinforced headtubes (see right) that we are so confident in our frames and are able to offer such an extensive guarantee to our customers.
