    Posted: Jan 28 2024 at 3:33pm
  I've recently acquired NPM 42898xx and am in the process of filling out a data sheet for it. Even though I have the set of Carbine Club newsletters, it appears that NPM wasn't a favorite subject of CCNL's (or collectors) as there's less info on them than many of the other manufacturers. The newsletters with the most NPM info were issued nearly 37 years ago so as well, so maybe there's some newer info I haven't seen. But the final word for me is from the cognoscenti here on this forum, THE most reliable source for M1 carbine info, IMO.
My best guess is that 42898xx was made at the end of NPM's production. The flat bolt is marked N 14, op slide N15 & the trigger housing N 16. The receiver lug has 23 stamped on the bottom.
CCNL 125 says that no original NPM has been found with the trident with ·N· triggers (Neptune Meter Co.), but then goes on to show the data sheet for the April COM #4426xxx that has one, as does mine.
CCNL 126 says that no type 2 barrel bands had appeared on NPM carbines as of the time of the newsletter (April, 1987). Mine has an unmarked, 4 weld, blue-black type 2 over a Marlin barrel with no sign of type 3 band shadow and an unmarked type 6 front sight that shows no signs of being molested. The front sight is a bit darker than the barrel. Additionally, 42898xx has a Trimble TN stock with factory-made low wood, similar to the late NPM Mike in NC described in his earlier post.



I'm trying to determine the finish on the sear, and possibly the hammer, which looks like case hardening, especially on the sear. Or is this just a variation of in-the-white?


It has a type 3 recoil plate marked WJ on the bottom that I can't find mention of anywhere.














The bolt, mag catch, trigger, hammer plunger, op slide spring guide, slide stop, butt plate screw and every pin and plunger I can see is blued. The finish type 3 SN marked safety nearly matches the finish on the trigger housing.

The rear sight is in-the-white, although in some of the pix it looks as dark as the receiver. All other parts are what would be expected in a late run NPM, but if anyone has any questions, please ask.
Muzzle wear is less than 1 and if the stock were ever sanded in the past, it was very lightly.

Thanks in advance for your thoughts on this one

Charlie

Say PingCMP, to address your concern about a lack of an updated NPM "manufacturer's update" article in the Carbine Club newsletters....there was never any lack of interest in NPM or UND or SG, etc., carbines.

But there was always a shortage of dedicated researchers/writers who were willing to spend the time and immense effort required to assemble accurate update articles that would stand the test of time. Some update articles took more than a year to complete!

Our last NPM update article (NPM 125, 126 in 1987) was an excellent product researched and written by Dave McClain, a pioneer M1 Garand collector and a founder of the GCA. Thankfully, he was also very dedicated to the Carbine Club.

By 2013, the few hardcore researchers/writers that we had left, were burning out and - unfortunately - no one was willing to step up and continue the great work they had started.

There is a lesson here; if collectors want accurate information on a manufacturer's carbines, they can volunteer their time and effort to research and write update articles. We've still got a lot to learn, but it all hinges on dedicated volunteers who will commit to time-consuming projects.

    I figured that the lack of NPM info in the newsletters was simply lack of reporting due to NPM not being as exciting or popular as some of the other manufacturers. The NPM updates in CCNL's 125/6 were very helpful in figuring things out with mine, thanks! Has there even been any thought of reviving the print edition of the Carbine Club newsletters? I have more spare time now that I'm retired, not not the knowledge or exposure to M1 carbines as many of those here.

Thanks again!

Any idea on what I should call the finish on the sear and hammer? I suppose in the absence of blueing, I'd call it in-the-white? Neither look parked but the  colors on the sear remind me of the bolt on my 1888 Springfield trapdoor.
Also, the WJ marked recoil plate is a head-scratcher, I can't find it anywhere in War Baby.

Thanks

Hi Charlie,

Re: the printed newsletters - by 2015, all of our researcher/writers were burned out and there were no manufacturers update articles planned for 2016. We need to give those guys a lot of credit for their time and hard work, especially because (with the exception of J.B. Powers), they were all still working full-time jobs while they worked on compiling update articles in their spare time.

By summer 2015 I didn't have enough completed articles, and no articles "in work," to allow me to plan for 2016 newsletters. Submission of data sheets and other material from the membership had all but ceased. I couldn't send out renewal forms, because I would run dry of material before the end of 2016.

Our membership was now spending their "carbine time" on the CMP Forum, MilSurp, and other forums. The "instant answers" and discussions to be found on the internet held the attention of collectors far more than our quarterly newsletters. The Carbine Club, as we knew it for 39 years, had run its course.

So I "shot the wad" with a large final NL 384 in Oct 2015 using up almost all of the material I had on hand.

Thankfully, Dan Pinto and Jim Mock volunteered to keep the Carbine Club alive by taking it online. They brought the Club into the 21st Century, where it needed to be. I had several military reports that Dan published to "prime the pump" of the new Carbine Collectors Club. He built the chat forum and Jim built the website.

So to answer your question, the paper newsletters are now history and will not be revived.

To answer your other question, historically, collectors have referred to those "case hardened" hammers and sears as "in the white" (just to differentiate them from blued or parkerized parts).

Your WJ recoil plate is a mystery to me also. If the finish wear on it is consistent with the rest of the carbine, and if the slot of the screw is not buggered up, I certainly wouldn't change it!

There are still a lot of things about carbines that we don't know. Many factory- original carbines, especially those by Std Pro, have been "corrected" incorrectly by collectors who were in a hurry to replace a part that didn't fit the pattern of other reported carbines. In my mind, if you come across a carbine with a "wrong" part, it is likely factory-original, because a previous owner - if he was a collector - would've changed out that "wrong" part. :-)

Regards, mb

Yes, it looks just like the pic in the thread you sent. Apparently it was another wartime contractor that flew under the radar. Thanks!

Exactly! I learned that lesson years ago when an otherwise 100% S'G' I bought had an IN marked type 3 safety. I bought van IP marked safety to "correct" it, only to find out about the transfer of IN safeties to S'G'. At least I didn't hammer off an original sight like you told us you did, long ago . . . ! Wink

Thanks, I'll finish up the data sheet for this NPM and send it into Dan

Regards . . .

The W on the WJ plates seems to match the W on the Wadsworth made plates, if anyone ever looked. 

Ping, Really nice NPM, Appreciate the share!

I would not put too much faith in stampings, especially if you see a variation or difference. This would be due to different stamps or the stamp manufacturer if they were not making the stamps in house.

Better to look at the machining shape and direction like I did in this post
The direction change would be unlikely within one manufacturer as they had jigs made to do the operations, so it would be consistent from that factory to all of those prime contractors that used them.

I did compare all of the "J" plates and compared to who I thought who made them. If memory serves there was one surprise. I will have to dig my notes out if there is an interest.

@PingCMP, I'm in the process of restoring a US&S NPM from a "U" marked receiver I bought from the Ruth estate. The receiver and a correct Marlin barrel I found look nearly new but I believe their finish is original. The only "correct" flip sight that I was able to find was a "TN" marked one like you have. Mine also appears to be "in-the-white" with a little more "patina" (rust) than yours. The contrast between the sight and receiver makes it obvious that this is a restoration but I don't plan to change anything.



Thanks for your post as it helped reassure me that the "TN" sight would be appropriate for this restoration, especially considering all the positive comments your carbine received. Your carbine will be nice addition to the Serial Number Spread Sheets, especially if you add a Data Sheet to this thread that other collectors will be able to reference.

If a sight is in-the-white and the receiver has darker original finish, there's bound to be a contrast, moreso in bright light. I believe mine to be 100% original. FWIW, my mag catch, trigger, and all pins and plungers are blued, yet the safety is the same color as the receiver, just like the NPM discussed in this thread that is similar to yours:


I sent a digital copy of the data sheet to New2Brass, I'm not sure where he posted it but let me know if you can't find it.
It seems that NPM's have historically been underreported to the Carbine Club, just like Marty Black once said about S.G.'s. I love them all!
