Our Assessment: This Irwin-Pedersen M1 Carbine’s receiver was produced in the first serial number block during late 1942 to early 1943, representing one of the most intriguing chapters of M1 Carbine production. Irwin-Pedersen was awarded a prime contract but ultimately failed to deliver carbines that met government inspection standards, and no completed Irwin-Pedersen rifles were formally accepted for U.S. military service. As a result, original IP-marked components are scarce and highly sought after by advanced collectors.
This rifle is fitted with an Underwood barrel dated 6-1943, and notably, nearly all other components, aside from the barrel and upper handguard, are made by or for Irwin-Pedersen. Subcontractors represented include Redfield Gun Sight Co., Star Watch Case, Wadsworth Watch Case, and Union Hardware, all of whom contributed parts during the brief IP production period. Whether this rifle left the factory in this configuration or was later assembled from correct and rare Irwin-Pedersen components, it remains highly collectible due to the scarcity of authentic IP parts and the historical significance of a manufacturer that never successfully fielded an accepted production carbine.
