Pre Phoenix back in the late seventies, when the new crankshafts were made by Gordon Allen, we all used magneto crankcases and machined a simple casting that took the place of the three bolt fabric oil seal housing. Hard to see in this photo as it is hidden below the gear driven supercharger and the Ulster style water pump welded to the front of a standard magneto model gear train housing. One of the two black flexible hoses from the external oil filter then feeds directly into the new nosepiece. Back then the crankshafts were supplied with a machined starting dog that easley accepted a modern lip seal.
