I'm prety much convinced that if Ettore went to all that Trouble to produce a full size drawing of the frame, he would of built one. The One in this french guy's collection, looks like the frame and forks are totally right. The Componants look like a mixture of english and french parts from a later period. Is the Drawing really 1913. Mmmmmmm.?????
