Thank you for your kind comments. As regards the horn I am in the process of moving it back to where it should be in front of the engine. Dave Owen mentioned the fracturing possibility as well.
The black does look good but to be honest I would like to paint it Olive drab as it would have been in 1942, but for the moment I am just checking and fettling things whilst enjoying the riding experience.
I love the unhurried ride and the low down torque.
