-SG- The latest edition of the Classic Motorcycle contains a fairly lengthy article (via this link) on this subject by well known journalist Alan Cathcart. Alan had the pleasure of a canter on Sammy Miller's example, the bones of which were imported from South America not long ago.
The article mentions four 'survivors' including the Fowler Fake in the NMM, about which we have probably written too much for the site already! Sad to say, it appears to me the other three machines mentioned are also of, shall we say, somewhat dubious parentage!
