    The Official IHC Serial Numbers Thread

    Guys,
    I invite anyone that has an IHC (in any configuration) to post it here and I will get it added to the master list.
    Please take these listing with a grain of salt. No way to know the history on most of these but as more and more are entered maybe some patterns will start to emerge.
    As I find Correct Grade, Collector Grade, or other verifiable Original rifles I will highlight them in Green so they stand out.
    Any consecutive serial numbers will be highlighted in Blue
    Also have added those IHC rifles that have been identified as having the serial number changed (8 stamped over a 3) in the past for unknown reasons. These actually occupy three lines each. The original serial number before it was modified. The new location with the modified serial number. And finally the rifle that may exist out there with the same serial number. These are highlighted in Yellow.

    Collecting the different varieties:
    A while back I started a Post on collecting the 9 (now 11) identified different varieties of IHC Garands, but as a simple Post it gets lost in the weeds so I thought I would add a link here in case someone wants to take a look:
    Collecting all the varieties of the IHC rifles - CMP Forums (vbulletin.net)

    Bogus/Fake details on IHC rifles:
    This is a link to a thread showing what I have seen faked on IHC rifles and will add additional as I come across them.
    Collectors Beware! - Bogus/Fake stuff on IHCs - CMP Forums (vbulletin.net)

    IHC Rifles with Over-stamped Serial Numbers:
    There have been a number of IHCs found that have had a numeral 3 in the serial number over-stamped with a numeral 8 and since those are being added to this list as they are found, here is a link to that discussion on the forum.
    IHC with an overstruck 3 in the serial number seen at the Show of Shows - CMP Forums (vbulletin.net)

    A note from Rolling Thunder for rifles in specific serial blocks:
    WANTED: Looking for these IHC Serial Numbers
    4461000 to 4471000
    4473000 to 4482000
    4484000 to 4493000
    4627000 to 4634000
    4644500 to 4648000 (Probably a Gap Letter)

    If you have an IHC in these serial blocks would you be kind enough to send a photo of the serial number and state its heat lot located on the right side of the lower receiver to Rolling Thunder via this Forum email. Just these serial blocks please


    Information needed for these lists:

    - Receiver Serial Number
    - Receiver Drawing Number & Heat Lot
    - Heel Stamp Variation
    - Barrel Mfg and Barrel Date
    - Stock Barrel Channel Date and markings
    - Owner name, or User Name, or if privacy is important just list "Forum Member"

    In speaking of this list with Dave McClain he recommended that we also include the Receiver Drawing Number and Heat Code in information posted. This extra detail will help a lot in identifying the ranges of the non-IHC made receivers.

    Receiver Type vs Serial Number information from Wayne Bradford will help you identify a couple of the more unusual Postage Stamp receivers:

    • Arrowhead - (4440001-4441100)
    • SA/IHC Postage Stamp - (4441101-4445557)
    • IHC/IHC Postage Stamp - (4407001-5197999)
    • SA/IHC Gap Letter 1953 - (4637500-4659999)
    • SA/IHC Gap Letter 1955 - (5198000-5211244)
    • HRA/IHC - (5213034 to 5217010)

    Note: Keep in mind that these types of details are still evolving somewhat so if you have a receiver type that falls outside the above ranges, I certainly would like to see it. Once confirmed the range can be adjusted accordingly.

    Receiver Heel Stamp Variation KEY to use:
    AH=Arrowhead
    SA/IHC= SA/IHC Postage Stamp
    PS=IHC/IHC Postage Stamp
    GPR= Gap Letter
    HRA/IHC=HRA IHC Postage Stamp

            Got it and a fine-looking rifle it is as well. Wish I had one like it.

                      Gentlemen,

                      In discussion and working with other Rob on this, I've stickied this thread as the latest iteration of the IHC Official Serial Numbers, continuing the excellent work of Brutus and wgandy.
                      Many thanks to Brutus for his work in compiling and starting this collection of data, to wgandy for carrying on the torch, and now Rob, to whom it passes from Wayne.

                      At first blush, I was going to delete the existing sticky, as the information contained in the charts here captures all the information from there...not to mention, it would still be available for data as we can view deleted threads/posts (much to the chagrin of some characters around here).
                      However, for those that want to look back on it for reference, it will remain here in the Garand section, just not as a sticky anymore...

                      Please use this thread to update any IHC information you may have.

                        Thanks, Rob, for your help.

                        Guys,
                        Everything updated in my Master List that has been submitted so far. I will update the posted list this weekend.
                        The interval for updating the posted list is still somewhat up in the air and really just depends on how many submissions are added over time.
                        Going forward I will date each update so you can see how old the info is.

                        thanks all,
                        the other Rob
