Hello All.
I think it could be considered a hybrid, a marriage of early and late. My first open crank, the aspirations of a young collector was a 2 HP Hit and Miss Bamford of the late 1920's. Once restored and moved on for a reasonable profit many more engines followed. This was the way I financed my Lister collection.
I've attached a picture of the more conventional Bamford layout, detachable cylinder head, 2 valve. The
" caged valve " system that had been used on the early " headless " engines was great for de coking but if left for long periods of time became seized solid!
Cheers Graham.
