-SG- My good friend Peter Thomson (Thomson Motorcycle Museum, Palmerston North, NZ) writes that he recently obtained a quantity of cycle (pushbike) stuff from an estate and amongst it was this Norton advert. It's not clear what periodical it first appeared in but it seems to date from 1910 or a bit earlier as the vee twin engined machine is also mentioned in the advert. Doubtless someone with access to appropriate sources of reference can date it precisely so let's be hearing from you!
