Saginaw 5.8 million date Born????? and Barrel question.

My CMP Inland was getting lonely. After all, I have two 7.62x39mm rifles, and two 5.56x45mm weapons. With that logic, I needed another carbine!

I have the Inland, which is the kind of Carbine my dad carried on Iwo Jima. Since he also carried a Saginaw for awhile (on Saipan, I think), I decided to build up a mid-war saginaw. I just acquires a 5.8 Million Saginaw barreled receiver with an undated IBM barrel (ME 3 or less).

What is the approximate date range of the 5.8 million saginaw, and what barrel would it have had. Did IBM ship any barrels to saginaw???? I realize it is probably a replacement, and that is OK. I am just curious.

Thanks in advance.

I have one stamped very likely the day the second block started. For that one, with undated Saginaw barrel, I'm guessing late February (or early March) 1944. Could be wrong though.

Good Questions. Here's the closest I can come up with. Mine. A pity someone messed with it. Saginaw undated barrel. Cheers. Mike.Attachment 19829Attachment 19830Attachment 19831Attachment 19832Attachment 19833
