I bet this post belongs here....M1 carbine parts markings.

[Topgun]

I just picked up a nice old carbine. IBM mfg. I've cleaned it and noted the parts markings and would like to know if anyone has a link to proper parts for proper guns. Tried a search on "M1 carbine markings" and got too much to search.

It's marked as follows:

No bayonet lug barrel: IBM CORP 10-43
Receiver: IBM CORP
Ser #: 3729XXX
Front sight: N
Operating rod: N
Barrel band: O (maybe Q)
Adj rear sight: JAO
Bolt: AOB
Trigger guard assy: IL (letters truncated)
Hammer: LTQ (or LTQ)
Safety: "EW"
Mag release: M
Recoil lug: WI (or IM) but the W sides are slanted...odd for an M
I-cut early stock: RMC cartouche crossed cannons
Upper handguard: RMC

I didn't pull the trigger itself out. Couldn't see markings if any.

I seem to remember RMC being a mark for Rock-Ola. Don't know if IBM made wood for the guns or not.

Very uniform finish and nicely old inside. Bore mirror clean. Insides haven't been oiled for a LOOOONNNGG time.

Also not sure if the old early I-cut stocked ones had adj sights. The last early I-cut I had had the flip up sight.

Any info appreciated. Just so many different markings on the parts makes me curious if it came that way.


I posted it in Rifle Country, but it's probly more a collector question.

If you want to know who made the stock take a look in the slanted sling well near the butt of the stock. Parts for IBM almost always had a B at the end of the designation on the part.

My IBM has mostly Winchester internals.
