    Been a while since I've been here, but will give it a shot.
    Looks like you've been waiting on an answer for a while too.

    The photos are a little blurry. Hopefully, my info below will help you sort it out.
    I'll try and keep this from getting too deep too since there's a lot of detail in the book section I'm getting this answer from.

    The Craig Reisch book says that the cannon on the cannon cartouche for IBM should measure 0.45" and be located near the pistol grip on the right side between the oiler slot and the pistol grip.
    Some Type I and II stocks were modified to low wood. They can usually be identified by a thin ridge where the high wood was removed, but not always. (If it's an "I"-slot with low wood, it's a Type I that was modified.)
    As far as the other stock marking, I will make the assumption that it is a Type III low wood non-potbelly stock with a short barrel channel (3.15"). (So you know, if there is a cutout for the "fun switch" and is a non-potbelly type, it's a Type IV.) All manufacturer markings should be in the sling well.

    Wartime replacement stocks (in general and usually all Type III) have:
    BR
    IR
    PJ
    J
    LB
    LW
    and may have a flaming bomb symbol.

    The Type III markings for IBM factory stocks can be one of these:
    BR-B
    JL-B
    LW-B
    SC-B (birch wood made by Sprague & Carleton Co, New Hampshire...he has it as Kane, NH, but I'm guessing it's really Keene)
    TN

    Yours looks like it MIGHT be one of the 3 upper markings for factory stocks, but I can't make it out.
    The Craig Reisch book is a MUST if you collect Carbines. It's very detailed.
    As far as other parts markings and who made them, you can do searches online and some of the sellers have done great research into who the spare parts manufacturers were and what their markings are. Don't get upset if all of the parts on your Carbine aren't IBM only. Lots of other manufacturers supplied parts to the main guys, and they came out new that way.
    I forget where I saw it, but either in the Reisch book or a website I bumped into, they discussed that anomaly in depth. There was a list, as I recall, of who supplied stuff like barrels or other small parts to get someone up to speed on their quota for final shipment. The rule I usually go by is, the major parts like wood, barrel, trigger housing, and receiver TEND to be the one manufacturer, but don't quote me on it. Arsenal rebuilds tend to be more of a mixmaster of everything. If it's got a bayonet lug, you can pretty much bet it's an arsenal rebuild. Only SOME late WWII Carbines came with those (Inland at 6,300,000 s/n, Winchester at 6,500,000 s/n range. All Quality Hardware with band marked MMQ and lug EM-Q are post WWII rebuild items.)
    Hope I didn't bore you!
    Good luck!

      ​ I was reading the above postings about the IBM carbine stocks, last month I sold a nice IBM hi wood carbine stock to an advance collector. Also I was informed by the collector that it looked like cherry instead of walnut. He said cherry was not common. I know that Rick B. has some cherry IMB stocks, most being modified to low wood. The carbine in the IBM stock is a Quality Hardware 1,6 million with Underwood July 1943 bbl

        I have a cherry JLB low wood stock on my IBM carbine. When I got the rifle, the wood looked different than walnut. I did some research and found that cherry was used by JLB. It is a nice looking stock.
