IBM M1 US CARBINE

Seller Description For This Firearm

The **IBM Corp. M1 Carbine** is a fascinating piece of WWII history—chambered in .30 Carbine, it served as a lightweight semi-auto sidearm for support troops. Here's a detailed breakdown:

Production & Rarity

* **Total IBM output**: \~346,500 carbines from Aug 1943 – May 1944 (\~5.7% of total M1 production) .
* Manufactured primarily at IBM’s Poughkeepsie, NY plant with some parts from Endicott, NY .
* Only standard M1 Carbines were produced—no paratrooper (M1A1) or select-fire M2 variants.

Identifying IBM M1s

IBM-made carbines have distinct markings across parts:

* **Receiver**: “I.B.M. CORP.” + serial number (typical range \~3.65 mil–4.00 mil) .
* **Barrel**: Stamped “I.B.M. CORP.” plus ordnance flaming bomb; often barrel dates “11‑43” or similar .
* **Small parts**: Bolts (“AOB” or “EM‑B”), hammers (“AMB”), trigger group (“BE‑B”) etc.—subcontractor codes followed by "‑B" denote IBM specifics .
* **Front/rear sights, barrel bands, handguards, stocks** all carry unique IBM-coded stamps .

Collectors prize examples with all matching IBM‑marked parts.

Yes if you're aiming for a collector-grade WWII M1 Carbine, IBM examples are relatively scarce compared to mass-producers like Inland or Winchester. An all-matching specimen with good mechanical function and bore can command a premium.

Tips When Evaluating

1. **Check serial & parts**: ensure “I.B.M. CORP.” stamp(s) align (receiver, barrel, bolt, trigger group).
2. **Verify part codes**: look for IBM-specific subcontractor stamps (“AOB,” “AMB,”)
3. **Assess stock/bore**: check for cracks, refinishing, bore condition—these significantly affect collector value.
4. **Matching parts**: recoil plate, sights, handguard stamps all contribute to "all-matching" pedigree.
