Your carbine was made in Grand Rapids MI by the Saginaw Steering Gear division of General Motors. Appears to be from late 1943 to early 1944. Saginaw made roughly 293,592 M1 carbines and made receivers for others assembled by different manufacturers. If you look on the top of the barrel, about half way between the end of the stock and the front sight, you may see a small stamped date. If the date is there, that is when the barrel was made.
The serial numbers assigned to Saginaw Gear(Saginaw) were 2 groups.Your group was serial numbers 3,250,020-3,691,519.These numbers were used for M-1 Carbines assembled from May-1943,thru Feb-1944.with that said I would conclude that your M-1 carbine was assembled in the year 1943.
