Trigger Housing

I have been trying to I.D. a trigger housing on a new acquisition and I can't find it in any resource that I have and was wondering if anyone here might know something about it. It appears to be a Type V with the oil hole in it. The only marking that I can find on it is a "R" on the inside bottom in an indentation between where the safety and the mag release go through. The rotary safety and the mag release are post war rebuild marked and I thought I would locate the housing there, but no mention that I can find.

One other thing that caught my attention was that it is a different sort of green than I have been running into and it seems pretty easily scratched.

Trigger housing? What trigger housing? I don't see any trigger housing!

Seriously, a pic or too might help

Look inside the mag well.....it might have a "U" in there. Underwood marked theirs that way rather than on the outside like other mfgs.

I had a "seafoam" or "institutional" green trigger housing once. It was a teflon coated one that went with the likewise light green teflon coated Universal carbine. Maybe that is what you have? Likewise Picure =1000 words...

Sorry, my bad. Was late last night when I quit peering at this thing through all sorts or light and all sorts of magnifiers. I did look in the magazine well hoping for the U as the books said, but nothing there that I can pick up. It came with an Underwood barrel but this seems lighter. Teflon seems to fit the bill, the older you can feel it teflon feel. Hope the pictures capture the color if nothing else.Attachment 23635Attachment 23636Attachment 23640Attachment 23639Attachment 23638Attachment 23637

I was thinking it was something like that but have never run across one or any parts to one......unless I have now. Oh well, if that is the only bogus piece on this thing, I'll be happy.

The pictures and/or my eyes aren’t clear enough, but maybe M2……possibly post war?

My eyes are heading south too, so what looks focused to me may be fuzzy to the rest of the world. It does have a M2 slide so I was thinking the same thing, but so far haven't tracked it down in the post war stuff I've looked at.

I can't really help from pic's, but look close on pic # 2 for a faint Inland logo. trying to help.

Your Trigger Housing is cast, notice casting lines through the middle of it. I dont know if any of the postwar USGI housings were cast, maybe someone does. Probably a commercial housing, IMO.

Using a green background and hoping to capture the green tint of Parkerizing would be considered an exercise in futility.

Thanks everyone. I'm pretty well convinced now that it isn't an issued or rebuild item so am already looking for a replacement. The nice thing is that this gun has so many different contractor's parts, any particular one, as long as it's USGI, will do.

Again thanks, I stared at this so long that I actually thought I saw a side profile of a revolutionary general imprinted on it.

Twas a pure white cutting board, perhaps the Ott light I used did something.

Not enough detail in the pics or on the rest of the Carbine to express an opinion. If re-built and the letter R is a dominant feature I'd be thinking Raritan, Red River or Rock Island. But, as I say, we need more details to help. Had a NPM with MR (Mount Rainier) on the stock ?. Send a macro pic of right rear of housing. Mike.

Oh well,

Will give it another try. Used another camera but same eyes and skill level, I do apologize in advance to those offended by poor photography. I think mpd1978 is right about it being cast and commercial. It scratches real easy and is shiny underneath. Thinking may be aluminium and coating not sticking on it real well. After I get a replacement, I'm thinking about removing coating and seeing what's underneath.


I don't know that the rest of the carbine would be too much help. I was actually just shopping for a stock for my Inland. This carbine had a Inland stock and the guy was going to change it out for me as it was just one he happened to have on it at the time. Originally he said he had a Winchester looking pot bellied stock on it and showed me that stock. I don't know much about those and wanted the Inland stock but in looking at the rest of the carbine, it had a lot of interesting parts on it and I ended up buying the thing. Receiver is SAGINAW S'G' and serial is 3247400's. Type I front sight marked N with the size 7 mark on the left side. The barrel is UNDERWOOD 8-43 with flaming ordinance bomb. Rear sight is Type III adjustable with H in a shield, staked in. I put it in my Standard Pro stock and metal and the rest is interesting research material. Type 3 front band with post war marking, Type VI slide with serial or part number 7161843 (M2). TypeIII.. Round bolt OI (waiting to see if I won auction on bolt tool before I can see what's inside. Rotary safety with post war marking. Type IV Magazine release and support with post war marking. Sear is type I BI, Hammer Type III AMB, Trigger Type II SG.

It is cast. The "R" may be for reproduction possibly?

Beats me. Didn't think there would be much of a market for reproduction trigger housings but now that I am shopping around for one and seeing the prices they are asking for GI one's, I can see where a buck or two could be made. I got my feelers out in a couple of commercial forums seeing if anyone recognizes it.

Must end this.

On a web site M1 Carbines Incorporated (m1carbinesinc.com), same people who do the Bavarian M1 Carbine Site, I found what I was looking for under the National Ordinance, Inc information. The make or made commercial M1 carbines out in California. Saw the "R" I was looking for and the trigger housing and this statement: "National Ordinance utilized surplus GI trigger housings as long as possible. When the supply ran out they arranged for Rimer Casting to manufacture an investment cast trigger housing to GI size specifications and dimensions. Trigger housings cast by Rimer can be identified by the letter R forward of the hammer, down inside the housing."

Will continue shopping for a trigger housing. Nope, I am not an obsessive compulsive. Or, that is what I tell myself anyway.

That's an outstanding site for finding info about commercial carbines. The amount of accurate info there is unbelievable. Before that site was put together info about commercial carbines was mostly secondhand and often unreliable or not found anywhere at all.

Just obsessively try to convince yourself you're not compulsive and you'll be fine.
I always win disagreements with myself and get my own way - (No you don't!) Yes I do! :madsmile:

I did send them an e-mail thanking them for all the work that they do and how helpful it had been to me. They have already replied, very graciously, and said they were glad that they had been helpful as that was the reason that they do what they do.
