Sorry, not much info on this engine.
I discovered a picture of it back then in the 'Model fourstroke engines' by the Late Mr. Peter G.F. Chinn, published back in 1986.
A so called prototype is shown of the engine with the folowing info:
Four lobe camshaft in it's cyl.head. Operate valves through L-shaped rockers.
I obtained the engine in the early ninetees from a close friend of Mr. D.F.Green in England. Have to dig in my lecture to recall his name. Think it whas a name well known from English model magazines.
I know, it's on my long term to do list, still have to go in search for any further info on this engine.
