Yet another coincidence seems to link us Michael. Was Napier North West London based, as I think my grandfather might have worked for them before he was headhunted to run the new Scammell works in Watford.
Napiers were developing the prototype Mechanical Horse but decided not to carry on. My grandfather certainly worked in aero industry, and had maintained planes during WW1, possibly for Napier.
By coincidence the Canadian part of the family had one mad crazy individual who used to take arial photos, while flying the plane, and I don't think the camera was bolted to the outside of the plane. When he got past retirement, he was told he could either continue flying the plane, or taking the photos, but not both. I think I met hem when I was younger anr they came over to UK on ocean liner. I remember picking them up at the old Southampton Liner Terminal.
