Nice firearms! -- And welcome to the forum.

I have an M-1 carbine my father brought back from the Korean War. Like yours it has the early "flip" sight. A LOT of those have been replaced during refits so you don't see them all that often. I like them better than the later adjustable types. The flips are smaller, simpler, and IMHO, more robust.
Mine has the type 2 barrel band which is wider than yours and has the assembly screw reloaced to the bottom, but lacks the bayonet lug found on the type 3.
The actuaotor slide on mine is also a later type (#4 IIRC) which has the more angled cam used to increase dwell time.
The stock on my carbine isn't quit as nice as yours -- yours looks almost brand new!

Interesting note; the photo that shows the .45ACP cartridges (2nd from last); I note the primers are convex. I still possess a quantity of .30 carbine ammo my father brought back from Korea, which was WW2 surplus, having convex primers like that. That's something I haven't seen on any modern ammo.

Again, welcome to GUNHUB. There's lots of good guys here. We're perhaps not as active as some other forums but the guys here know their stuff.

Very cool, and props for your photos.

I noticed that about the .45 ammo, it's actually in nice condition but I don't think I would attempt to shoot it.

Same with the 1943 .30 carbine and 30-06 ammo, I will leave them as display items.

I believe that ammo is corrosive.

If you're refering to the .30 carbine ammo, no, we never made corrosive .30 carbine ammo in America.
If you're refering to the .45ACP or the .30-'06, then I shall remain silent as I don't know about those calibers.

bearcat6 · 03-20-2015, 08:22 PM

You are right about the 30 Carbine I forgot that but I think the other stuff was corrosive until sometime in the fifties.

2k05gt · 03-21-2015, 12:05 AM

Like Bearcat6 said, all military primers except .30 Carbine were corrosive until the early 1950's.

Twin Cities Ordinance AP M2, headstamp TW 43 (1943) Brass case
Western Cartridge Company, WCC 45 (1945) also brass case

Notice they both have the concave primer like the .45 ACP,
or not?

the .45 ACP Info.
EC 43 FMJ
Bullet weight-227.7 grains
Powder-5.4 grains
Domed appearance of primer
OAL 1.260
Crimped to .470
Made by the Evansville Ordnance(Sunbeam) plant

the .30 Carbine Info.
PC 43 FMJ
Made by the Kings Mills Ordnance plant

Here a list of NON Corrosive Lot Numbers

My carbine has all the post-war mods, and I've thought about restoring it to the original state. The problem would be finding and regulating a flip-up rear sight. I'll be delighted to learn how they were zero'd for elevation.

I've had a magazine for this rifle and several rounds of E C 43 ammo in my gun cabinet for years and never knew what it went to. I aquired it from my dad who probably got it from his. About a week ago our elderly neighbor was cleaning their basement and gave me a large box full of paper shotgun shells still in the original box and several odd caliber shells including an m1 8mm magazine with about 10 rounds. So this sparked my interest in what do all of these rounds and magazines go to and I stumbled on the pics of this gun at the top of this discussion, looks just like the one I have..Anyway, I will never own one of the firearms that these rounds and magazines go to so what is the best way to put it in the hands of somebody that may need them..

A really nice looking display, but did notice a few items that are a bit too late for 1943. Examples would be the bandoleer, stripper clips, and the box of (LC-'71) Vietnam era Carbine ammo. Did NPM ever use Type 4 trigger housings? - Bob
