Ever wonder why during World War I the "P" Proof Mark wasn't stamped on US Mosins or American Enfields?
Apparently, there was some objection from the Ordnance Department about using it on commercially supplied rifles.
It turns out that an employee from Remington was the one who suggested using the "Ordnance Echelon" (or flaming bomb as it's more commonly known) in its place serving a dual purpose.
