WWII Mess Kit Knife hallmark

[The_Brick]

Hello,

 

I recently purchased a mess kit knife but I am having difficulty figuring out who the manufacturer of the knife is. The hallmark looks like three flowers. Any help identifying the maker of this mess kit knife is greatly appreciated.

I have a mess kit knife with the same hallmark. No other markings but “U.S.” on the opposite side of the handle.
