2nd Pattern

 

This has the top flap with the short straps.

 

The 1st pattern, which I do not have, has a short strap that is riveted to the flap, rather than sewn. It also has a ring on the end of the shoulder strap to attach to the suspenders. This design can be seen in the M1941 Manual shown at the beginning of the thread. Marine_Kabar / Greg will post one at the end of this thread too.

4th Pattern

 

The Korean War version remained unchanged from the 4th Pattern, 1944 version, except for the material / color change. It is unmarked or date stamped. The straps taped together to make a musette bag was done by the Marine that used it and I left it as is.

Knapsack

 

2nd Pattern

 

This version has the pack flap with short sewn straps. It is hard to say where it was made but it was probably made at the USMC factory in Philadelphia, PA in the 1942 - 43 contract period too. As you can see it is rather "salty".

Knapsack

 

2nd Pattern

 

This version has the pack flap with short sewn straps. It was made by Boyt in the 1943 contract year. These packs are usually not marked so the Boyt marking is an exception to the rule.

If you want I can post pics of the early war Phila Depot M1941's plus the early suspenders with early hardware.

WW2 Suspenders

 

I've seen four styles of buckles on these

 

1. flat cast bronze

2. flat but made of tubular shaped brass. Narrower than #1

3. curved and narrow and made of brass

4. curved and wider and made from a brass colored metal but definitely stamped and not cast.

 

Color of the webbing runs from the pre/early WW2 USMC specific tan that has an organish tint to it to an light green. And I have one pair that is a definite mustard YELLOW color shade. Early production had all brass hardware but during WW2 they started substituting steel for brass and you often see suspenders with a mix to materials used.

 

Here are pics of an early M1941 set of suspender probably made at the USMC Phila Supply Depot
