Hello,
I'm working on the restoration of my 1949 Mk3 Standard. The bike is in Argentina as many other Mk3's. The image shows the tank as exactly it looked when I stripped the paint under 2 or 3 coats of black over 50 years.
As far as I know there a discussion about what colour was the stripes on wheels and tank. Some say it was white and others say it was a mixed option.
I hope this will help you.
All the best
Gabriel
