Vee Twin with Rear Cylinder Removed in Featherbed with front tubes removed .
Is a P&M Panther "Sloper" motor (bang at every lampost). It never was a twin.
Popular with the double adult sidecar folk. So managed to keep in production until 1967.
Not sure why anyone would want to slip one into a fb, unless it was just what they had in the shed?
