Any comment on this?

Looks like you answered your own question to me. There is a US military equivalent. It's not cosmoline. I'll have to dig out my can of it and read the print.

Was wondering if LITHIUM GREASE N.L.G.I. No 2 is correct?

That's what your research says. The NATO code is the same. I'll comment later if I can find my can of US military stuff.

Here's a commercial product that meets the specification:

Found my cans of US military rifle grease. Same age as me! They're marked:
GREASE, RIFLE
MIL-G-46003 (ORD) AMEND. 2

Thank you very much for your help Brian.
