The M2 was most likely stamped before the machining of the receiver was complete.

Mike,
Your IP sure does look like a N2.
The spacing does not look right for a M

Take another look. It appears that he "M" and "2" were separate stamps. If you study several of them, you will notice that they are not stamped evenly. It appears that the "M" in question, is actually stamped upside down.

Chris,
If you look at it and think the M is upside down, the spacing does then work out and I agree with you it probably is a M. I guess your job with the CC and your personal experience and collection would give you a leg up on most of us in the numbers of IP's handled!!!! I've only had my hands on a few, and seen what's on the web. Thanks for pointing that out about the stampings.

Actually, I haven't studied I-P much. Just getting up to speed now. Here is a picture of the marking on 1773393. Notice that the "M" does not have serifs. Also, another, partial "M" appears to be stamped sideways over the "2".

I pulled mine out 1.776 it has a 12-42 Rock-Ola barrel. I didn't break it down but a did notice a crisp flaming bomb with 5 punch marks right above wear these M2 stamps are located

Curt,
Looks like yours, Newscotlander's, and Arceiri's all have that. I'm on vacation, so my carbine is 4,000 miles away right now to check mine.
Chris,
Thanks for the info on yours. Interesting on the M stamp. I tried to get a pic of the stick figure, but I was in a hurry to leave for vacation when I was taking the pics. Pretty sure the CCNL is #284 for FP's info on the figure. Let me know if you need anything else info wise. A pic of my M2 stamp is in this thread.
What is this ?

Umm.....

My flaming bomb is upside down! What's with THAT. Must have been struck late on a Friday afternoon or early Monday morning. Actually, I suppose the manufacturers were working 24-7during the war, although I have not seen anything in print to indicate that.

But I would ask if S'G' were to get receivers from S.G.,wouldn't they be marked as the Inlands were on the left side with an S.G. stamp?

I came back to this Great old post and have to wonder...
IF S'G' would have got receivers from Saginaw.
Wouldn't these Saginaw receivers of had the WIDE REAR LOCKING TANG?
Like the earlier Saginaw to Inland and later Saginaw to S'G' receivers?
And like Bruce noted the SG Stamp on the lower left side of the receiver?

Thx,
