Locating a French Adrian helmet factory

[DaWhale]

I am trying to find the location of a factory in France that produced Adrian helmets during the first world war. A 1917 film from the French Images defense government website shows the entire manufacturing process at this factory, and I remember hearing something about manufacturing differences between companies that made these helmets. Also, some helmets have what appears to be a serial number, although I really wouldn't know since I'm not an expert on these kinds of things. Does anyone know what company owned this factory or what the number means? Can the number be used to track down the factory or company? Any help would be greatly appreciated.

The film can be found here: https://imagesdefense.gouv.fr/fr/la-fabrication-des-casques.html# (The file is too large to attach here)

Here is a screenshot from the film showing a helmet with a number on it:

Several factories were involved in the manufacture of the Adrian Helmet. The first one to successfully produce in large quantities was the Japy Factory which, according to one source, was in Usine. You may find these links a useful starting point.

Usine  being French for factory. But of course you know that.

From French Wikipedia:

These helmets came from the Japy Frères factories in Paris (rue Albouy) and Beaucourt, near Belfort, and from other companies (Reflex, Jouet de Paris, Société des Phares Auteroche, Dupeyron, Compagnie des compteurs, and Bonnet, on the boulevard Beaumarchais in Paris) and were designed with the help of Louis Kuhn, head of the mechanical stapling workshop of the Japy Frères establishments.

No I didn’t but just trying to be helpful to the OP which is more than your unnecessary and sarcastic comment is.

Jouet de Paris were a toy company, I wonder what British toy companies were making for the war effort. (I did think Japy Frères were too, but they have a background in industrial horological production. Another case of bad memory on my part.)

Out of period, when paratrooper helmets were made in WW2, they were manufactured by Briggs Motor Bodies in Dagenham, a panel beating subcontractor who were eventually taken over by Ford UK.
