The top of the barrel is marked “SAGINAW S.G. DIV. / GENERAL MOTORS” and “P”. Saginaw S.G. supplied undated barrels for Saginaw S’G’ (page 50). The trigger group is marked “S’G’ ” on the right rear which was used by Irwin-Pedersen and Saginaw S’G’ (page 78). The hammer is marked “S’G’ ” which was used by Irwin-Pedersen and Saginaw S’G’ (page 89). The magazine release is marked “SI” which is an Inland mark (pages 100-101). The smooth push button safety is unmarked which is consistent with other manufacturers (page 95). The inside of the operating slide is marked “S’G’ ” which was used by Irwin-Pedersen and Saginaw S’G’ (page 65). The bolt is marked “S’G’ ” on the right lug which was used by Irwin-Pedersen and Saginaw S’G’ (page 36). The front sight is marked “N” which was used by Irwin-Pedersen and others (page 56). The Type I rear sight is marked “S” which is consistent with Saginaw S’G’ and others (page 29). The Type IA barrel band is marked “KV S’G’ ” which is a Saginaw S’G’ mark (page 59). The underside of the Type I handguard is unmarked which is consistent with Irwin-Pedersen and Winchester (page 138). The sling well is marked “RSG” which was used by Irwin-Pedersen, Saginaw S’G’ and Saginaw S.G. (pages 108 – 109). The top of the grip is marked with a small “flaming bomb”. The left side of the stock, above the trigger, is marked with a Rock Island Arsenal Rebuild stamp “RIA / EB”. The right side of the buttstock is marked with a “crossed cannons” cartouche and “S’G’ in a box”. These are Saginaw S’G’ marks (page 124”).

Barrel Length: Approximately 18 Inches
Sights / Optics: The front sight is a bladed post set between 2 protective wings. The rear sight is a Type I dual flip up aperture. The rear sight functions, but has been installed backwards.
Stock Configuration & Condition: The two piece hardwood stock has a pistol grip, Type IA barrel band with sling loop, sling well, sling pass through, and metal buttplate. The refinished buttplate has light surface erosion and small dents showing through the new finish. The sling loop shows scratches and is bent. The stock shows several scrapes, scratches, and compression marks as well as sanding marks. The wood has been oiled. The LOP measures 13 1/4 inches from the front of the trigger to the back of the buttplate. The stock rates in about Very Good overall condition as refurbished.
Type of Finish: Parkerized
Finish Originality: Original Receiver. Refinished Parts.
Bore Condition: The muzzle and the grooves near the muzzle are light gray. The rifling is deep. There is erosion at the muzzle and light erosion in the grooves. The bore shows an M.E. of 2.2.
In this writer’s opinion, this bore rates 7 out of 10.
Many military and C&R eligible weapons have bores that will show erosion. This is not only due to age but to the fact that corrosive primers were commonly used in ammunition worldwide. For example, the U.S. used corrosive ammunition throughout WWII. The U.S. military did not begin to phase out corrosive-primed ammunition until the 1950s.
Overall Condition: This rifle retains about 92% of its metal finish as refinished. The metal shows scuffs, small scrapes, and a few small scratches. The sides of the trigger group show small areas of thinning. The left and bottom of the receiver each show areas of pin prick surface erosion. The receiver shows discoloration from oxidation and a spot of thinning on the left. The barrel shows thinning under the barrel band. The action shows operational wear. Most of the markings are well defined. Overall, this rifle rates in about Very Good condition as refinished.
Mechanics: The action functions correctly. We did not fire this rifle. As with all used firearms, a thorough cleaning may be necessary to meet your maintenance requirements.
Box, Paperwork & Accessories: The rifle comes with a green canvas sling and a 15 round magazine. The magazine appears to function correctly.
The 15 round magazine is not available to residents of California or any other state with magazine capacity restrictions.
Our Assessment: The M1 Carbine was developed and produced after WWII started. Over 6 million were made by a number of U.S. companies to assist with the all out war effort. The M1 Carbine was widely issued to U.S. Military Forces which numbered over 16 million during WWII. The M1 Carbine contributed greatly to U.S. efforts during WWII.
Irwin-Pederson M1 Carbines are RARE. Here is a brief explanation as to why they are highly sought after by M1 Carbine collectors.
Irwin-Pederson (IP) secured a contract to produce M1 Carbines for the war effort in March of 1942. Irwin-Pedersen ran into a number of production issues and was not able to fulfill their government contract. Saginaw S’G’ took over the Irwin-Pedersen facility in April of 1943 and produced M1 Carbines using Irwin-Pedersen and Saginaw S’G’ parts. Irwin-Pedersen had assembled only 3,542 guns at the time, none of which were accepted by the government. Any completed Irwin-Pederson rifles were most likely reassembled and reinspected by Saginaw S’G’ after they took over the contract.
There are 2 separate Saginaw Gear manufacturers. Both were Divisions of General Motors but were located in different cities. Saginaw Carbines made in the original Saginaw, Michigan factory are marked “S.G.” or “SG”. Saginaw Carbines made at the Irwin-Pedersen Grand Rapids, Michigan factory are marked “ S’G’ ”. Saginaw marked the Grand Rapids factory M1 Carbines S’G’ to differentiate them from the ones produced at the original Saginaw plant.
This Irwin-Pedersen M1 Carbine was made during WWII. It has since been rebuilt and its parts have been refinished. It retains several of its Irwin-Pedersen and Saginaw S’G’ parts. The Saginaw S.G. barrel is original. Irwin-Pedersen and Saginaw S’G’ did not produce barrels. Saginaw S.G. and other manufacturers supplied Irwin-Pedersen and Saginaw S’G’ with barrels to assemble M1 Carbines with at the Irwin-Pedersen factory. This rare Irwin-Pedersen M1 Carbine will add nicely to a WWII or M1 Carbine collection.
