Even if you have no interest in ordnance material watch this short movie for its historical value.
This appeared on BOCN (posted by MINENAZ16) and is a circa 1916 French short movie (appears to be digitally remastered) of the production of 76mm/3 inch(?) shrapnel shells & fuzes at Vickers Ltd. in England.
The movie demonstrates the huge human workforce, many of whom were women, required to supply the war effort.
For those who don’t know, when you go to the above web page and start the movie, click on the small rectangle at the bottom right corner of the little movie screen to set the movie in full screen viewing.
