My very close friend, Jacques Barlerin, who who passed away in January was probably THE best specialist about the French military ammo.
This gruesome event is still a cruel loss for those who had the luck to know him.
He wrote a very informative booklets about the French experiments in intermediate cartridges, but did not published it, only in 5 to 10 copies. So it is unpossible to obtain it to-day. He was also preparing a whole history of French military small arms ammunition, bu I doubt that this masterpiece could be published a day…
We have the project to edit the whole array of studies he made on the French ammo subject, but it is now up to his survivors to decide what will be the way to do it and if I may quote some parts of it, as I did to-day, I do not wish to reprint it under any kind of authority before things are settled.
