    Recently I had an email from a gent in Australia who was trying to ID an engine that is in his fathers possession .
    I have not got a clue so I said I would post it on the two forums that I use and maybe get a bit of help for him

    Any chance somebody knows what it is ?





    A little info that was supplied

    · Engine Rotation: counter clockwise
    · Bore: 4 .5 inches. Stroke 4 .75inches?
    · Twin camshafts.
    · Side Valve
    · Roller cam followers
    · External Oil system? total loss( this is missing from engine)
    · Duel Ignition: ? Magneto +?
    · Cone clutch
    · No manufacture marking or stamps on the engine
    · Big ends have 4 bolts on each, which go through the rods and threaded into the rod caps with lock nuts.
    · Rods made from? Bronze like material and has no big end bearing, runs in the rod material.
    · Crankshaft mounted in the sump.

    I have allso posted this on Fozzers forum

    Dual ignition would suggest aircraft, I think,and the water jacketing looks lightweight,too. Reminds me a bit of the Liberty V12 in "Babs",the old LandSpeed record car at Pendine.
    Just my random thoughts.

    Hi everyone,
    I seem to remember a similar engine on display at the fleet air arm museum, it was from a german airship, I believe.

    An early Maybach then ?

    It looks a bit heavily built for a flying machine. My first thought was it was an early "supercar" engine. And most of those were of German origin.

    I like the idea of cranking it over with that starting handle. A job for chauffeur !

    Yes I was thinking its a bit on the weighty side for aviation with that honking great flywheel! I would think possibly very early commercial vehicle. Some of those omnibus engines were works of art.

    What price a racing power boat engine? The exhaust stubs look just about right and a big flywheel is necessary with a small high speed propeller. Dual ignition would be a seamanlike precaution in such an environment.
