Hi Maridadi, thanks for your kind words.
Yes, the DKW is a brilliant example for the sophisticted engineering in the immediate pre-war era... the Gilera Rondine, AJS V4, Velocette Roarer (Arthur provided a pic of it recently in this thread), Benelli 250 four etc etc...
on the other side, I admire very much the 91 mph lap of Harold Daniell in the TT of '38 on a rather simple gardengate Norton....as brilliant as SMBH' s 108.77 mph lap nearly 30 years later, perhaps even more....
sorry chaps, era out of thread but I'm not sure if it's worth to start a new one...
