Hi Doug,
although I've been looking for it for a while, I've never found anything about the 'Fee' other dan later text referring to it as the first name of The Fairy. The picture you mention, would that be the same as the one on page 5 of Briercliffe and Brockways 'Douglas motorcycles' ? Unfortunately there seems to be no logo ore name on the tank of this machine....
I'm wondering if there ever was more than a single prototype and the subsequent production models were all Fairies?
regards, Michiel
