Frankincarbine? a.k.a. Mixmaster of Sorts

Semislinger · 12-26-2007, 09:56 PM

Hello all, I'm new to the this forum but I've found it's pages very helpful in identification of my new M1. I've been a mostly modern firearms guys but I've found myself getting into older ones as of late.
Here is what I've got and what I've been able to conclude from my research.
IBM M1 Carbine Serial # 38212xx
Barrel marked IBM Corp with P stamp
Push button safety marked EPB
Trigger frame group marked EB-B
Mag Release marked EPB
Bolt marked AOB
Sear marked BOB
Hammer marked WMB
Firing Pin marked OBB
Extractor marked WB
Slide marked AOB
Front sight marked N
Trigger marked SN
Mag marked AI with lines across above and below.
Adjustable sight marked IR CO with serial number 7160060
I think everything is IBM but the trigger (NPM) ,the front sight (might be IBM), rear sight (not sure) and mag. Oh and I forgot the Rock-Ola lug catch at the back of the receiver.
The thing is that the carbine had a stock conversion to a aftermarket stock with cheek pad and conventional sling swivels. The upper stock part appears to be original but has been re-finished and sanded with poly.
There is no bayonet lug or stock band on the front. I've seen carbines with and without bayonet lugs. would this one have come with or without.
See the attached pictures....
Let me know what the correct stock would be for this IBM as I want to get it as close to original as possible.
Thanks

Probably better off just buying a potbelly stock and get her back to shooting condition. Thats a darn shame what they did to that War Baby

99.99% of all carbines went through an arsenal rebuild after W.W. II. Any carbine you find with the original receiver maker's parts in it has been made that way by somebody with too much time and money. Any carbine turned in for repairs to Weapons Techs was fixed with whatever part was first out of the bin. Weapons techs did not and do not care who made said part.
In any case, only IBM and Quality Hardware made all their own parts. The rest used parts made by the over 1600 sub-contractors who made parts.

I only paid $250 for this carbine. The guy who sold it had no information on it. I guess I'll just keep it as it is and treat it as a shooter. It'll make for a good plinker.
Thanks

Leave it the way it is or just get a relacement stock and handguard. Even if you restored it, everyone would know - there would likely be a ring on the barrel from the bayonet lug and there would be stake marks on the receiver from the sight. Flip sights were not staked.

Dookie....flip sights were not staked??? I beg to differ! Most were staked with a chisel mark but a few had round staking right at the jucture of the base sides and the dovetail that used a punch point directly on the edge of the dovetail so that both the dovetail edge and the sight base were "cratered". you need to do a bit more research....

Also nobody made all their own parts. The most was Winchester Repeating Arms and Saginaw Steering Gear. They made 15 of their own parts each. Quality Hardware made only one part the receiver. Rock-Ola made 13 parts. The reciever, barrel, handguard, stock, gas cylinder, bolt, trigger, sear, recoil plate, firing pin, trigger housing, extractor and op slide. So it is not unusual that even "original: Carbines have different parts on them.
