The chap didn't paint over the original white, it was used by The Air Marshall team, there's a pic of it on my Kirk website http://www.haydn-automation.co.uk/Kirk-Brochures.htm
and the frames came in a number of different colours. White just happened to be the most common one in the UK.
It does look great in white, especially when built with modern components and as someone else mentioned earlier, you attract attention every where you go!
The reason the frame has an unconventional downtube is because CAD studies showed that torsional twist within the frame follows that line. More development history is on my site. Simon.
