My NPM M1Carbine (pic heavy) opinions welcome!

Yes, after about the 50,xxx - 55,xxx or so serial number range Inland receivers have two notches.

Are my old eyes, late at night seeing welding on the receiver?

If you're seeing what I saw in the lower left of the last two posted pictures, yeah, I saw them too. The gurus say we're wrong..........
So we must be mistaken...........?

The discoloration towards the "top" of the receiver? It's varnish that someone applied to the old springfield stock at some point. It was everywhere. I have been cleaning it off, little by little.

Serial numbers were applied toward the end of the receiver manufacturing process. If a receiver was completed enough for Inland to apply the serial number before being transferred to another manufacturer it would easily be identifiable as an Inland made receiver. However, the receiver shows none of the Inland receiver features and all the NPM features. The font in the serial number is not the style Inland used in the 5 million block either. The forward receiver markings match NPM markings which as you might have guessed differ from Inland's.

I am coming to this conclusion as well. Everything is standard NPM,..... except that serial number. I'm at a bit of a loss, if this has never been an issue before. Heck, maybe the "5" stamp is a factory mistake? I would be interested to see an inland with a serial number close to this one, just to try and look at this from another angle.

Yes Phil, that is the area I was seeing. In addition to the discoloration, I see what looks like welding slag in a couple of other areas. But even if it's been welded, it wouldn't account for the mis-match of the s/n & manufacturer's name.

Are my posts invisible? Which picture/areas? I am not seeing anything in the last two. I'll try and get a closer look for clarification.

Just throwing this out there. Any chance its a Winchester serial numbered reciever? They have some blocks of numbers that one book I have shows close to this but the block listed is incomplete in the book. It only shows ending numbers and no beginning in this range? Just a thought otherwise I surely do not know..Does not look like their font however.
