Inherited Dad's M1 Carbine, an Irwin Pedersen

Allard j2, is there a blue-green ink stamped number in the bottom of the stock slide well? I'm liking the looks of your IP but the trigger is throwing me off

Since the trigger didn't have the usual notches on the backside, I thought it might be one of several hundred that were transferred to IP from Inland and Underwood. I'll try to post a pic of my S'G' trigger if I can locate one. Nice Carbine! - Bob

PS. Yes, on your understanding of transfers.

USGI, would S'G' have stamped an Inland trigger (or any other manufacturer's trigger) with their own proprietary marks?

I don't know the answer to that, but have often wondered of the possibility - especially in this case, with Inland and Saginaw Gear both being divisions of General Motors. I have seen S'G' hammers and triggers with slight differences in the markings and was never sure if that was legitimate, or not. Here's a composite I made for comparing the OP's trigger marking with mine. - Bob

Maniac: No, I don't see any blue-green ink stamp inside the stock.
USGI: I don't know about the trigger, it's all new to me. I disassembled it for the photos and to document what it is. Now that I know it's of interest, I'll have documentation on what's inside it. The following web page has a photo (with arrows pointing at two differences) of a notched IP trigger The U.S. Caliber .30 Carbines - Parts Below the photo, it says:
"Triggers produced at Irwin-Pedersen and Saginaw Gear at the Grand Rapids (S'G') facility may have one or two characteristics specific to the triggers manufactured on some of the tooling at this facility."
I guess in this instance, their use of "may have" means as implied, "may--or may not--have."
I would say... damn, I wish "my" gun didn't have any questions about any items on it. But then I have to think, I'm lucky to have inherited Dad's guns, and pretty lucky it is what it is.
Seems like--just guessing of course--that any transferred parts would have been marked by the company that made them. Unless they were pulled off the line before marking and then shipped. ?

Yes, that's my understanding too, and that's what is typically seen - although there are examples of parts that have been overstamped. In that case, it's often hard to tell which stamp was placed on the part first - some of these have been shown here on the forum. - Bpb

The trigger notch wouldn't worry me that much. One of mine is barely there. It should also have a tooling line on the right side of the tang about half way along it but not quite half way. The tang engages the safety. Look for that line.

As viewed from the side (as in the website photo mentioned above) it would appear as a vertical line on the right side. Looking at it from the top, it's more like "a step" in that long trigger tang. So yes, from the side it has a vertical line on the appropriate side, in the appropriate place, that the photos of the other company's triggers do not have.

Could it be that Saginaw S'G' was gradually taking steps to eliminate the--imperfections for lack of a better word--that had given the Irwin Pedersen group their quality control issues and gotten their contract taken away? If it has the line and not the notch, maybe there are others the same, after S'G' corrected/eliminated whatever tooling difference was causing the senseless notch? That's a WAG, of course. Wild assed guess. Probably where rumors and non-documented information originates. And why would the other references be calling it "a line" when it's a sharp stepped change in thickness? I'd call that a sharp edged step. If I'm looking at the right thing.

Only one hammer mark. How much better can it get?

Very nice, thanks for all the photos. In my opinion if you had to go out and replace that gun you better have 4-5 K to spend, minimum.

Here's a price comparison of one that sold on GB a few weeks back. A cmp post war rebuild with extra parts so you can return it to original configuration. { no Comparison } !!
