    I m trying to identify a plane who fall in ITALY at the end of 1943 close to MONTECASSINO (at 40km west).
    The only element element I have is that it was a single engine fighter plane
    I have 2 pieces of the body were I could find theese references :
    73-14308-4 whithin letter of 4mm high
    just beside another reference in a circle where I can read . 943
    and another circle where I can read HT 20
    Could somebody help me to identify this plane, or the way to identify It.
    The pilot has been saved during 7 months by my grandfather till the US army passed over Montecassino.

    Hi Tiptop;

    Can you take a photo of the circles that read 943 and HT?

    I took a picture enlarged to see the reference but they are in the same main piece , the piece on the right in the main picture.

    I join also a picture of the motor "axe cam", I m trying to find out which type of motor it comes from Merlin which type ? Allison which type.

    Any information would be precious and thank you for helping.

    Thanks Tiptop - I now have some information for you. If you notice "943" stamp, above the 9 there is the letter "A." That is part of a North American Aviation stamp from what I can determine. The HT 20 is a heat treat stamp and it also matches a North American Aircraft format. The part number has me thrown off a little but I believe it's from an early P-51 (A-36) or B-25. Based on finding the camshaft however I'd guess it is not a B-25. I'll try to identify the cam shaft for you if one of our other members beats me to it. Based on the time and place of your find I'd guess it's an A-36.

    Here's what I believe the full stampt to look like.

    Here a picture of an installed Allison camshaft - I think it matches.

    Just a complete guess from me but could the '73' of the serial number refer to NA-73 and be the type number?

    Thank you very muich for helping me

    For the cam shaft, my picture shows :
    1 support
    2 cams with different angle

    1 support
    2 cams with different angle

    In the picture of the ALLison and also the merlin, i have also some picture not so beautifull and they show :
    2 supports on each side of the 2 cams

    The is why I m not sure it's such a motor

    I was looking a picture of the Merlin 45 which équiped SPit mark V

    For the circle with the reference, did see the same circle on other planes or currently its the North american fashion ?

    IT could be an A-36 , because the 27th FS was équiped with
    It's sure it's not a B25 , because it was a single engine fighter plane
    I don't really beleave it's a P51, the brend new with a modern look, some people could remember

    The first digits were usually given to a production segment or section of the airframe. Most P-51/ A-36 prefix numbers were higher, but there were always exceptions to this rule.

    This was a typical NAA stamp used in their production line. There were also stamps specific to the aircraft program but that stamp seems to be the standard stamp from what I see.
