So it does! Missed that. Thats enough evidence for me. Roundal on one side and Group marking of B/21 on the other side of the tank. RAF & number on the front numberplate as already mentioned.
What size of roundal looks best? Also what size and font would you suggest for the lettering? Hopefully my favorite stencil supplier is open for busines. Lost touch with the old signwriter guy I used to use. Rgs - Jon
There is nothing on the primary chaincase side of the fuel tank I'm afraid. There are photos of the tank posted on the WD16H & Big 4 website if you are interested.
The roundel stencils are a right fiddle on the double curvature of a tank. I went with 1" digits on the Big 4 and 1 1/4" on the RE. Both bikes have a 3" roundel but 4" might be nice if you have room.
