I am working on an engine that was writen up in Model Engineer magazine back in the late 1950's. The design for "Newbury" is from J.N Maskelyne. And the articles are by Martin Evans. I have the full size drawings and all the articles except one. That is in the issue from 19 December 1957, on pages 821-822. If anyone knows where I could find a copy of this issue, I'd much appreciate it.
