I just got the WM20 I bought through Robb Nortier last summer. It's complete, has had a partial repaint perhaps 30 years ago, and should run. The frame looks dark blue-green which I presume indicates RAC. I will be posting photos.
Frame is 74429, engine 106807. Does anyone have the C number for this bike?

What I have done is have my C number painted on the tank, I have the bikes post war registration number painted on the back mudguard, and the bikes modern registration number painted on the number plate fixed to the back mudguard.
That way I feel happy that the bikes three identities are carried on it.
