Charles Cleghorn’s picture of the Ellis Boyce Norton
7 December 2012
I enjoy your magazine very much. The following may be of interest

The 1963 post-TT issue of The Motor Cycle held a minor item on Ellis Boyce’s Senior Norton. The bike carried him to a respectable placing and he reported a trouble-free ride. It was then noticed that a central section of the megaphone had broken away, leaving a clear gap of some six inches. Surprisingly, the now-isolated rear end of the megaphone, retained only by its single locating bolt from the support stay, had not been shaken from its position, staying in precise alignment with the separated front end.

With no loss of power noted during the ride, the obvious questions arise – had the exhaust gases ‘jumped the gap’ and allowed the system to function as designed? Or would any such motor run just as well on a truncated open pipe? There was no photograph, so not enough detail to stimulate debate, as far as I recall. However, I knew I’d snapped the machine in the finishers’ enclosure but mislaid the print and soon forgot all about it.

Now for the Rip Van Winkle moment… Rummaging through some old papers a few days ago, there it was! Just 49 years on. So, is the megaphone a cosmetic accessory? Come on, you gas flow men, rocket engineers and such, what’s the answer?
