OK, here's a curious coincidence that might bear on Roy's comment that Nesbit Robinson's S1 Douglas did 100 mph at Brooklands.
A few years back we discussed how Pullin's development of the S1 lead, in March 1922, to him becoming the first rider of British soil to exceed 100 mph.
https://www.douglasmotorcycles.net/index.php?topic=7014.msg27563#msg27563 To do this, he arranged to be timed over the very unusual distance of half a mile at Brooklands; usually the shortest recognised distance was 1 km. And the man who set up the electronic timing equipment at the record attempt? None other than Col. Lindsay Lloyd, the man who, just a couple of weeks later, was to sponsor the Public Schools MCC race meeting at Brooklands (see above).
There are many things I don't know about all this! But I do like the (unproven) idea that our top photo shows Nesbit at Brooklands, maybe at the Public Schools MCC meeting in April 1922, just a couple of weeks after Pullin had broken the 100 mph barrier. Col. Lloyd was the president at the PSMCC, he also timed Pullin, maybe Herbert Robinson presented a trophy to the PSMCC where his son Nebit was a member? If so, everyone knew everyone.
Re-reading Roy's last post I see I've misunderstood: what if Nebit's fancy bike - a road-going S1 Douglas with twin carbs and an airbox, as ridden by Pullin, the fastest 500 in the country - did do 100 mph at Brooklands, but not with Nesbit on it? (I was puzzling the impossibility of young Nesbit doing 100 mph!)
Was Nesbit's racy S1 Pullin's record-breaker, sold to Herbert Robinson, Douglas agent in Cambridge for his son?
That would be a good story.
