WWII USGI M1 Carbine Recoil Plate Marked PR-B IBM Machined Type 3 Original
**Original WWII USGI M1 Carbine Recoil Plate – Scarce \"PR-B\" Stamped Marking**
**Premium Machined Type 3 Component - Factory Correct for Prime IBM Restorations**
Up for sale/sale is a 100% authentic, original USGI World War World II M1 Carbine Type 3 machined recoil plate. This highly collectible piece features a beautifully defined, crisp factory-stamped \"PR-B\" manufacturer code located cleanly along the side extension arm.
The \"PR-B\" code is an incredibly scarce variant. While manufactured by the Canton Forge division of Poor & Co. (\"PR\"), the vital \"-B\" suffix denotes that this specific production run was delivered directly to International Business Machines (IBM) to fulfill their prime manufacturing assembly quotas.
IBM M1 Carbines are among the rarest and most fiercely sought-after collector models. If you are completing a period-correct, high-dollar historical IBM rifle restoration, generic subcontractor parts will hurt your build\'s value. This genuine \"PR-B\" stamped plate is exactly what you need to ensure pristine factory accuracy.
**Item Condition:**
* **Finish:** Retains its exceptional original dark gray/black military parkerized finish. Shows beautiful surface consistency with very faint, honest wear along high friction points from historical handling. Completely free of rust or structural pitting.
* **Threads & Lugs:** The interior mounting screw threads are sharp, deep, and entirely unstripped. Engagement lugs and indexing blocks are crisp and structurally perfect.
* **Marking Clarity:** The full \"PR-B\" stamp is exceptionally deep, crisp, and 100% legible under magnification.
Please carefully inspect all the high-resolution macro photos provided to judge the stunning cosmetic condition and undisputed authenticity for your collection.
