Hi Erik,
You will find an article about Granville Grenfell’s Scott-Morgan Special in Yowl volume 3 no. 6, August 1963, on pages 8, 9 and 10. It is accompanied by a Klemantaski photo of the front of the car under construction, and a diagram of the coupling chains and sprockets.
There is a road test in Motor Cycling in October 1936, which was reproduced in Yowl dated July, 1959.
Regards,
Carl
