1934 500 cc Rotary Valve Motorcycle Engine
« on: 01 Jan 2008 at 11:24 »
I am in the process of getting some drawing together of a Douglas project from 1934.

Fore and aft Twin of 500cc
Bevel-driven cylindical rotary valves (similar to Cross engine.Was there a link ,as they were near neighbours?)
Air-Cooled with water-cooled G.A. arrangement also.

G.A. Drawings need a lot of work as they are hazy pencil on mucky tracing paper.
Some detail drawings are proper finished articles,so maybe something got built.

Has anyone anything at all to say about this project ?
