Sorry to break into your discussion unannounced.
My name is David Morrill and I am a writer and motorcycle racing historian. I found your postings on J.A. Jock McNeil. There were two Jock McNeils racing in the States in the early teens. Jock McNeil from Scotland, and J.A. Jock McNeil from Canada. To make things even more confusing, they both raced English JAP engined racers in 1912-13.
Jock McNeil, from Scotland, was killed in a racing accident at the Atlanta Motordrome board track in 1913.
Canadian J.A. McNeil, rode for Cyclone, after JAP. He then went to work for Excelsior Motorcycles, and developed and rode their OHV 8 valve racing engines. He did serve in World War 1, as a motorcycle dispatch rider. He was injured, and one of his legs was amputated. I believe he returned to Excelsior, as an engineer after the war. Don't think he raced anymore, but I'm not sure. There are several pictures of J.A. Jock McNeil, both as a racer, and team engineer in Stephen Wrights book on the board track racing era American Racer 1900-1400.
The attached photo is the Canadian J.A. Jock McNeil on his JAP racer in 1912. The author of the caption, miss-identified him as the Scot McNeil. This happens quite a bit.
The death of the Scottish Jock McNeil is documented in a story on the Atlanta Motordrome on my Deadly Dave's Blog. This link should take you to the story.
