    Could O..ine number be E..ine number, meaning engine number? This could identify the actual aircraft if anyone was to come up with some possibilities as USAAF accident reports log the engine numbers like the British Form 1180's.

    Hi Pete,

    Taking Channel as the declared crash site there were 70 B-17F losses.

    54 were built by Boeing at Seattle
    4 were built by Vega at San Diego
    The remaining 12 were by Douglas

    Date range was 16/02/43 to 24/04/44

    The USAAF records are rife with location errors ie the Channel reached up as far as Denmark and the North Sea started at Brest! So the above list is not set in stone.

    There is one Douglas built B-17F with a Newhaven link as this was where the crew was landed.

    16/08/43, 323BS/91BG, B-17F-35-DL, #42-3213, 2Lt E J Smith crew, ALL AMERICAN

    Just incase any one is interested here is a brief run down of what GM and Fisher Body did during the war.
    Even thought it does say B17F do we know this is the aircraft and not a production model of this particular manifold

    "I don't have a record of the items produced by the score of other General Motors divisions but I discovered that its Fisher Body Division alone
    contributed a remarkable assortment of material to the war effort. Twelve Fisher plants were assigned for use by other GM divisions and other companies such as Boeing and Firestone. The remaining 13 plants, mostly in Michigan , tallied up production numbers such as these:

    Aircraft assemblies, such as wings and tail sections, were produced for 5,214 Mitchell B-25 bombers.

    In Grand Blanc , 17,213 tanks rolled off the assembly line, most of them the famous General Sherman .

    Over in the Grand Rapids plant, the assembly line produced 2,359 anti-aircraft guns and later 550 huge 5-inch guns for the Navy's ships. They also shipped out over a half million high-explosive 55mm shell casings, plus aircraft and tank components.

    In plants of the Ternstedt Division of Fisher Body, a total of 293,100 intricate gyro aircraft instruments were manufactured. The division also produced
    1.2 million parts used in fighter plane cannons.

    Five Fisher east coast plants were merged into the GM Eastern Aircraft Division and was the source of three-quarters of the nearly 18,000 Wildcat and
    Avenger planes produced for the Navy carriers.

    In Cleveland, a 400 acre plant was built for assembly of wings, tail sections, ailerons, flaps, tail gun turrets and other parts for the huge B-29 bombers as well as parts for tanks and Naval guns.

    Also pouring out of these facilities, along with plants in Flint , Lansing , Detroit and Pontiac , were such items as 200,000 rocket fins, 86,000 droppable
    fuel tanks, 1,500 cowlings for Navy fighters and 9,352 huge crankcases for diesel engines to power Navy ships and submarines."

    Default That manifold

    Just a thought on this particular item. If it is indeed a manifold (engine exhaust, or possibly to do with the GE supercharger) then any serial number (that is an individual number peculiar to that manifold alone of all the manifolds constructed on that production line, and NOT a part number) would have nothing to do with the associated engine itself (aero engines certainly had their own unique serial numbers as they required individual logbooks and/or servicing cards and had to be closely monitored throughout their service lives). My guess would be that manifolds would probably NOT have individual serial numbers, but would certainly have a part number, contract number, specification (as has already been mentioned) and possibly a batch number, although the contract number itself would probably have this function. Inspector's stamps would also be typical of items such as a manifold which would have to be closely inspected on completion. However a manifold was not an integral part of the engine except as a complete unit, and would have been manufactured at an entirely separate factory, almost certainly by a specialist firm under contract to the War Department.
