Hi Marcel,
That is a very interesting website, just read the first two parts of the MOM story. My grandfather, now sadly long gone, was invalided out of the army during WW1 and then worked for the War Agricultural Committee in Sussex, on all the tractors and steam engines under their control. He used to tell me about the early Ford tractors, and trembler coil ignitions, etc. How I wished that I had asked more about it all, at least I know where all the enthusiasm I have for these machines, comes from !
regards, Richard
