'IP' Trigger Housing on eBay - opinions?

I've spent the last 10 minutes or so looking at this TH and checking my Riesch book. I see something that doesn't look right. What do you guys think? - Bob

M1 Carbine Saginaw S'G' Irwin Pedersen Trigger Housing NOS M 1 | eBay

Well it's not an IP trigger housing as it was made by Saginaw Gear and so marked. The packaging was left over from the IP contract. This would have been one of the spares that were made.

Yes, I noticed that but I'm puzzled about the width of the magazine wall and the lack of the bevels on the rear mounting lug. Is it a Type 2 or Type 3?
Thanks! - Bob

I have a real one (IP) on my mixmaster Inland that came from the DCM in the 1960's. Not selling but it is fun to have a piece of trivia.

It's a type 3 housing that SG used after finishing the left over IP type 2 trigger housings. It not a fake.

Type 3....Saginaw used a narrow wall, not a full width wall.

Here's a couple pictures of my Saginaw 'Grand Rapids' Type 3 housing. It's different than you guys have described, but I think it has to do with the transition as the locating hole gradually became smaller, and then just a dimple. Mine was probably made later than the one on eBay, and that may explain why it has the full width magazine wall. - Bob

Here's a pic of the trigger group on my 1.871xxx S'G', please pardon the cat hairs!

Hope this helps

That's an interesting one, USGI. I haven't found one with the unmachined locater hole like that. I've seen similar but quite like that. It has another feature I haven't seen.

What's the other feature you haven't seen? I see differences in the milling for the side contours leading up to the mag wall. This last picture might show how the hole eventually disappeared on the later guns. What's the S/N on that one? Mine is 1,829,xxx and Maniac's is 1,871,xxx. It looks like yours has the later hammer spring, too. - Bob

This one's in a 1.84, but I don't know that it's original to it. I doubt it. All the parts look original to the trigger housing (except the trigger spring of course). The other feature is the mag catch cut out. S'G' and IP have a pronounced cut back in the back side of the catch well. Some are probably more noticeable than others.

It's interesting to see another S.G./S'G' triggerhousing I have one like it in my spare parts box. Mine just came as a stripped housing. I never was sure just where it would fit in with production carbines. Mine looks like S.G. sent some started housings to S'G' and they finished milling them at S'G'. I really don't think S'G' changed their milling process to the S.G. style that close to the end of carbine production. They may have been doing goverment work but they were not part of the goverment. They needed to make money not make work to survive!!!!!!

Which pictures above show the S.G. style of machining? Thanks! - Bob

Here are the styles I have. Note which are rear bevel and which aren't. The machine hole from top to bottom is small divot, large divot, straight thru hole and chamfered hole. ETA: That top one is beveled rear.
