M1 Carbine help

first off i just found this site and let me tell ya it seems like a cool place :clap:

but i need a bit of help trying to figure out what my Carbine is worth (it is on my list of will never sell)

from what i have found out (my guessing) it is made by underwood but the SN is that of an Inland #480-XXX but it has Underwood stamped on the reciver and BBL most all marks i have found have a "U" other than right below the Underwood and the SN it has a "T" marked on it.

the BBL has 1943 stamped on it but the wood has no markings. the guy i got it from said his grandfather brought it back from the war and stuck it under his bed. here are some pics i hope they help :confused:

thanks for your help guys. oh i will post what i bought it for after i get a few replys of what people think its worth. (it was WAY under what i think i should have paid)

Interesting find. The round bolt and barrel band with bayonet lug are later upgrades added sometime after it left the factory. The stock appears well sanded, so that would explain the lack of markings on it. Check in the sling well on the left side and see if there are any markings in there. A photo of the receiver markings would be helpful, too.

Just curious ....with it having the upgraded barrel band/lug why would it still have the flip sight? Why wouldn't they have changed that as well?

mash man,

Welcome to the carbine forum. There are many knowledgeable and helpful guys here. We also have a search feature up in the tool bar that lets someone look up past posts on different subjects.

Nice looking carbine. Could you have missed a digit in the serial number? Underwood did make carbines in the 4 million range. And they could have the pressed trigger housing. A 400,000 Inland should not.

The RP marked base on the leaf sight is interesting. Is the leaf marked RP as well? That could be a big dollar item all by itself. Have you taken it all the way apart? Markings on the other parts? You need a bolt tool to check the firing pin and extractor.

If you don't already have one, a book would be a big help to you. A lot of new carbine owners start out with the Craig Riesch book, about $20 on Amazon or Ebay.

Nice pictures of everything but the serial number on the receiver close up. It could be an Inland receiver. Put tape over the last two numbers.

i will for sure when i get home. i am stuck at work right now :(

Depending on when the upgrade was done and what parts they had available at the time, a rear sight might not have gotten replaced. It isn't unusual to find a carbine without ALL of the possible upgrades done.

i will do what ever it takes to find out what little gem I may have found :sos:


so what does the RP stand for anyway? how much is that worth?

I want to shoot this little thing I have fallen in love with it but also if its a great piece of history I don't know I want to take a chance of messing it up :surrender:

Shoot it and enjoy it! You will not mess it up. These were serious weapons in their day (and still are), made to stand up to many thousands of rounds and combat conditions. I have a excellent "as it left the factory in 8-44" Winchester, and I shoot it every chance I get. I even carried it as a patrol carbine in a high country security contract. The 30 carbine round is superior to any of today PDW (Personal Defense Weapon) rounds, and excels under 100 to 150 yards as a CQB weapon. Read the thread on the Korean War Medal of Honor winner. He used it well.

My dad carried an M1 Carbine on Iwo Jima, and every time I shoot mine I feel I am shooting and experiencing History...

Is that target with the sight on the short (100/150) leg, or the long leg.

It looks like somewhere along the line the serial number has been removed and replaced with the one shown. You can see grind or file marks.

Underwoods T code (Intertype Corp) serial number range is 2,355,000-2,400,000

The Irwin Pedersen rear sight is worth a couple hundred dollars on it's own.
