    Dear All,
    we have some kind of a cannon in the mountains, probably used once by a Lightning.
    We thought that the number found on the surface would make it possible to asign the cannon to a Special Lightning and her Pilot.
    But number on the cannon D-28254-30, we learned fast is not indicating a special plane and her Pilot. Just like the numbers on Browning MGs do.
    But where is the identification number hidden on a Cannon.jpg Cannon.jpg cannon to asign the cannon to a special plane and her pilot?
    Many thanks for your replies.

    Best

    dnalor,

    This just does not look to me like the M2 cannon that was used on a P-38. Here is a link to the manual for the M2, which includes some photos.

    Notice the M2 cannon was quite long. The M2 was gas operated, with a gas cylinder above the receiver and barrel. There would be a hole in the barrel so the gas could go up into the cylinder which would then push on a piston. That action would eject the spent shell and load the next shell. Even if the top gas cylinder is missing, the gas escape hole in the top barrel should still be visible.

    Factory example of the 20mm AN-M2 aircraft autocannon used in the P-38. The men standing in the room near these cannon add scale to this photo regarding the length of this weapon.

    File cannot be opend/found.


    The unidentified gun is sticking deep with its barrel in the soil.
    It looks dismantled and we have no reference gun for such a status.


    The B/W Foto is showing p-38 . cannons.

    The length of MG2 cannon: 2m 38 cm.
