pre WW2 Springfield M1 rifles

[RCS]

Group of pre WW2 Springfield rifles with solid butt plates. How many
gas trap rifles are in this photo ?46825

Four?

[RCS]

less than four

2 on the chair, the rest look (hard to see all from the glare and the monitor I am on) like standard M1's

[Sunray]

The gas trap was discontinued long before the Rifle made it to mass production. Primarily because the gas trap required a great deal of extra cleaning time.
Supposedly, only 18,000(depending on the source. Some say 50,000.) gas trap rifles were ever made and most were destroyed by the U.S. Army in 1947. The rest were rebuilt using the gas hole and Production rifles used that gas system starting in late 1940.
I see 2, for sure, the picture angles are off to see if there are more. However, the receiver S/N will matter. There is a lot of fake stuff out there.

where did you get this info?

my understanding is most were rebuild in 41, new barrel, gas system, and welding the fix for the 7th round issues,

my 3 digit serial number, shows both the weld mark, and has a 41 dated barrel,

my brothers 3 digit serial number as well (he was reparked and rebuilt later (or more often) than mind)

both work as they should,

Appears to be three in the photo. Sincerely. bruce.

bruce is correct, there are three gas trap rifles serial numbered: 12K and 42K still missing some parts needed to complete and
a 41K serial number that has all original parts and is complete now. Gas trap production end in July 1940 but gas port production
started in June 1940468264682746828

How many gas traps in this photo? Wish you could see the photo in large enough detail, but under magnification every rifle appears to be a gas trap.

Actual photo is 27" long.

Excellent photo of the pre WW2 weapons, also very rare photos of the 1937 Model 1918A1 BAR with the
first bipod that was issued. This model BAR entered and was use in the early part of WW2 until the newer
model entered service.

photos show the 1937 BAR bipod, quite rare to find !4682946830

An old battler in the 36000 serial number range that probably went through several rebuilds, and finally ended up with FED. ORD. INC. on it's right receiver leg.

Thanks for posting your extra wide rib receiver, there are only around 12 known that have
surfaced over the past 15 years. They are all in the 36K to 45K serial number range. Unknown
as to the reason - lost in time - . Mine came from the CMP auction years ago and is still
without the 7th round correction, it is serial number 42593. Here are some photos468324683346834

Are there any other owners of M1 Rifles with receivers with that extra wide rib on the left side ? If so please post
as I am keeping data on these rare receivers
