WWII USMC Experimental Jungle Bladder Help

[Ryan B]

Hey Guys! I recently got this Experimental Jungle Bladder to add on to my Experimental collection. Both the Bladder and the case are dated '44 and USMC. Its in pretty good shape other then a little rust staining in the back. If you have any information on it please post because I would love to learn more about it! I'm not really sure if its rare or not? I also posted this on USMF its just i would like multiple opinions lol.
Thanks
Ryan

G'day Ryan
All I can say is it can't be common and I've only seen an Army type 45 made by "The International Latex Corp" in one of my reference books, it also states that there where a few experimental types tested from 43.

Thats what i was thinking also that they have to be rare becuase i've only seen one in my lifetime and this was it. I did a little research and nothing came up while looking it up. So i have no idea
Thanks

Bump for the morning. Anybody else know?

Looks like a 1940s version of a camel back

Also like a modern hydration vest but with straps .

Bump for the evening crowd. Still any info would help!
Thanks

I have seen a lot of these but almost all the ones I have come across are marked US instead of USMC and usually are dated 1945. These do not demand as much money as the experimental canteens but they are on the endangered list

Thanks Ben! So how much would one of these run around price wise with these sort of markings, shape wise, and rarity?
Thanks Again

The regular Army ones I have seen in various conditions from 35-65$, being that this is marked earlier and USMC I would say a bit more but I am not to sure, USMC things go crazy on fee bay.
