I was fortunate whilst restoring my bike to find parts with original paintwork to colour match. The colour is correct for very early war period bikes, although it is quite a 'nice' colour full-stop. During my attempts at getting the colour correct I must have mixed around 10 litres of paint most of which I still have sitting in my workshop awaiting a suitable 'green' building project. I have now had the colour professionally matched by Kerry at Warpaint and it will be available shortly if anyone wishes to use it, at the moment there is not reference number: I should have this next week.
Obviously in photos it does not look as good but here it is to give you an idea of the 'flavour' green it is
