1944 Laird Schober OD7 first aid kit with contents.  Is this a Jungle Kit for the Army or Marines or both?  Can not find much on the maker either.  Appears to be unused and NOS.

Any particular value to these by design, maker or date?

Jungle First AId kit and used by both the Army and USMC. Still see it carried in Vietnam by the Marines and at times the SEALS used or preffered this and see it attached to the back of the H suspenders.

Here is one worn by a SEAL on the back of the ( right side of photo)

 

The kit was first developed and issued during WW2 and continued in service throughout the Vietnam War though contents were updated. Yours appears to be a late 1950s-60s issue. The pouches changed as well as the contents. You can actually find WW2 pouches that were NOS being issued with the updated components as yours appears to be. Some actually with updated FSNs ink stamped on the pouch.

To answer your question regarding collector value around maker or dates, the WW2 kits are worth quite a bit more as their components are are more complex and have become more difficult to find over the years driving up their cost. Sulfadiazine (WOUND) Tablet packets and Atabrine vials bring quite a few $. The Iodine in the wooden containers and Frazers Solution (for athlete's foot) all bring several bucks more than any of the 1950s/60s components in the later kits. Also the first year (?) 1943 M2 pouches, which are a bit smaller in size, are more difficult to find and bring a premium. I don't believe manufacturers make much of a difference but I'm personally not that much into these kits. I hope this helps. 

Here are two from Iwo Jima (pic #1, Harold Keller, center & #2, radio man far left) and two from Korean War (pics #3 & 4).

Nice kit. Looks like it was packed in the 1960s.

All.  Excellent.  I had no idea they reused or made use of existing pouches into the 1960s.  Kinda figured a one-n-done thing for them and not thought of unused pouches being filled for the first time later.  Cool
