'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
