Lehigh ammunition in US service

Is “Lehigh Inc.” the same as “Lehigh Defense LLC.”? To my understanding it is.

Here the website of the latter:

They are offering a variety of AP projectiles (if I got it right along the Anthena design).
Also they have a US ammo manufacturer code which is “LHI” (as Lehigh Inc. as per the 1999 edition of MIL-HDBK-1461A).
Here the section on their AP projectiles:

Question:
Has anybody ever seen any packing material or even headstamps featuring “LHI” in a lot number?

I don’t know the answer to your questions, but I find it interesting that they are investing in .375 AP projectiles in lieu of other more popular calibers they could make. Mostly for .375 CheyTac, RUM, or Ruger, I presume? Can’t imagine use in .375 H&H or Wby Mag.

Matt, the .375 is given as CheyTac. Maybe they made them for a particular customer?

Alex, they are not related. Lehigh Inc. is a much older company that made metal parts for rockets, mortar shells, artillery shells, &c. during WW2, Korea and Vietnam. It was absorbed by Victaulic in 1967.

As you can see, the 1999 edition is a “little bit” outdated…

Fede, great info!

Then another question: has “Lehigh Defense LLC.” a US/NATO factory code?

I don’t know, I have never seen a box with a lot number using a US DoD style symbol or initials.
