Just to correct and fill in a bit more of this machines history, Derrick Genge Shire (NOT Derek) was not the owner after Catchpole. Arthur Breese owned and sprinted it after him but never achieved the same speeds, so he sold it to Derrick who kept it for many years. When he died Margret (another odd name spelling), his widow,passed it on to me. I was very concerned about what I considered to be dangerous and very extensive lightening work done by Derrick, as even the blades of the front brake and clutch levers were full of holes! In addition the frame had been very crudely modified, and I never sprinted it. I eventually sold it to Patrick Cravos a few years ago. I hope this sets the history books straight.
