Howdy all. I live in Seaside Oregon. I have two carbines, one a National Postal Meter and the other a Universal. I am presently refitting my NPM with NPM parts. My NPM has an Underwood Barrel 10-43, a NPM Bolt with NPM parts, NPM slide, NPM slide spring guide, NPM Stock marked Trimble Tn. with the NPM cartouche on right rear of stock, hand guard marked TN. Recoil plate marked n?.
I am joining this forum to learn more about my gun and yours too and shop for NPM parts.

Thanks, Tom

Thanks for the replies all. I bought this gun about 10 years ago at an Oklahoma Gun Show. It came with a replica folder stock with USGI steel on it. So basically you are saying that the real value is in completely original carbines or nearly original is where the value is at? If that is true I will end my quest to out fit this one with NPM stamped parts. I am going to need another barrel in the future. The S/N on my receiver is 4106xxx and the barrel is an Underwood marked 10/43. I have a gas leak at the piston nut due to loose threads. The piston and nut are new. I took it to a welder to weld up a small crack near the clean out hole. He advised me to clean out the piston chamber real well which I have done and then while slowly screwing in the piston nut apply red thread locker in the clean out hole to fill up the threads, then let it sit barrel tip up for 24 hours. I haven't fired it yet but plan to this week weather permitting. The recoil spring is new. My Gunsmith fired it several times and it fails to return the slide all of the way back to catch the next round in the magazine. He attributes this to gas leaking past the threads. Thanks much for you help. Magnafique

Thanks Tommy Gun, and Kevin. A couple of days ago I purchased a 248 page book entitled United States .30 caliber field guide for collectors. I have the manual you suggested Kevin.

Again thanks,
