Gentleman, Please understand this is coming from a carbine enthusiast point of view rather than that of an NFA guy as I am sure the points of collectability are different.
I am in no way making an attempt to disparage this carbine, I am just sharing what I see.
@JimC, please look carefully again where you got the 7270650 serial number, it is a Winchester and that range did have M1 carbines.
The serial range is not far out of line serial wise with Inland that it may have been a handstamp, however, I believe this to be a roll stamp.
If you look carefully you will note all the numbers are slightly shorter than the letters giving the appearance of being lower.
Very early in the 7M range, Inland was done with an M1 contract. Wound not make sense to keep hand stamping from a time perspective.
The only requirement of M1 or M2 marking was for the carbines going out the door of the prime contractor. All the Winchesters were overstamped. If you think you have a Winchester that does not have the 1 please take a very good look. sometimes it is well covered by the 2. If you truly think you have a non-handstamp Winchester M2 I would love the opportunity to inspect some pictures.
The military did not use the designation on the receiver to determine what model it was. They used features alone. If it had a selector switch it was an M2. When they converted an M1 they did not overstamp a 2.
Most m1 carbines went through a rebuild. The M2s, converted or actual, saw a lot of action after WW2 and been through many overhauls. I suspect the receiver being a true M2 adds value in the NFA world, However, it is clear that the carbine, on the whole, is not original as it left the factory.
It does have correct USGI parts for Inland M2s with the trigger housing, and selector.
The U round bolt with a hole in the bottom is a 50s USGI contract bolt for the rebuild programs. The slide is believed to be made by High Standard Arms, though it has not been confirmed beyond a reasonable doubt. It would not have come out of the Inland factory.
The hammer is not USGI. The disconnector may be a foreign contract. Note the number 2 in the C. I have observed other numbers in a C on disconnectors. I have also observed the same markings on recoil plates. We know these are post-war due to a slight design dimension change. This suggests the disconnector would be from the same manufacturer and time frame.
The stock is a late war style pot belly which has a distinctive shape to it. It was made by Overton for Inland. To some like myself has somewhat of collector value. If and when I get an M2 I certainly would want that stock for mine. Unfortunately, in my opinion, the stock has been devalued as someone added embellishments to it.
My conundrum of obtaining an M2 is that if a collectible receiver and on the odd chance of finding an original I would then be hesitant to shoot it. What fun is there to that. If I obtained an original barreled receiver I could just correct it to original parts. I doubt that would add value from an NFA point of view. It might also not be the best idea as it may not be the best combination for getting the timing just right. (unless you had access to many correct parts).
I once passed on a registered trigger housing because I was under the assumption that the ATF may take a dim view at some point as it is not one of the "Special" parts
Anyway my thanks to Dave for sharing this carbine with me.
