-SG- Leon is Australia has forwarded this photo of Herb Durkin - about whom there's a fair amount on the Internet, worthy of a quick read - seated on a 1930 DT Norton. The photo is via the Herb Durkin Collection of David Dumble in Melbourne. I was on the point of mentioning that only one DT Norton shows in the records as having been sent to Australia when I had another look at the photo - from which it seems quite likely that it was taken in New Zealand where perhaps Herb was on a visit at some time. Be that as it may, the photo shows quite clearly the through bolts holding head and barrel to crankcase and, not quite so clearly, the hexagonal exhaust nuts threaded into the exhaust ports, both features of the production DT Nortons.
