Larry,
I did not understand what your point was.
Of course, "pyroxylee" is not required to be marked on the gun. However, it is the *only* French word which applied to Nitro-cellulose based propellants in the early 1900s. Nitro or any derivative is just not in any French dictionary of the period and Smokeless or "sans-fumee" is way too vague and decidedly not scientific. By the way, Nitric acid was actually known as "acide azotique" in that time frame, Nitrogen is still "Azote", therefore Nitro anything was a non starter (except for nitro-glycerine which was a trade mark I believe).
By the way "poudre", even though widely used is not correct either, as the T is not really powder but comes in flakes.
As for the proof in the PT, I was looking for the actual regulation text which is the only way to actually prove this.
Anyways, I guess it's time to call it a day.
Best regards,
WC-
