    Great information especially about the change at 1002. Believe it or not but Steve and I have T24 1002 here in Oz and I believe that the changes noted above at 1002 must have been rolled out on vehicle 1003 and above. ORD 1002 is described as a Cargo carrier light T24 not M29. I will take a high res close up photo of the ORD plate for you. Not much remains of 1002 but I can confirm that the radio terminal box is located in the early position. See attached photo.

      Very interesting. That confirms what the book says.

        When looking at your list it appears you may have compiled it from the parts books. These are not always correct.

        Some of your starting ORD numbers are not correct.

        1002 should be 1003
        2102 should be 2103
        3102 should be 3103
        4202 should be 4103
        "H" plate on shift mechanism came in at # 2369
        OD paint started at # 3248
        Vented transmission cover came in at # 2369
        Track tension spring leave added at # 3452
        Differential housing drain added at # 3450
        Weasel production ended at M-29C # 15426 ( Total Weasel production 1,5424 units,...... T-24, M-29, M-29C models )

        The data for these numbers comes from the Ordnance Department Project Supporting Papers ( PSP ) Files in the National Archives.

        I will add some more comments later as I am somewhat pressed for time right now.....

          Yes, I have compiled the list from the parts book and TM 9-772 and TM 9-1772.

          I will update the list with your information.
