SWAG on my part, but I just surmised that the design was an easy step from the previous generation black powder cartridges. Perhaps even a compressed BP small bore case that was never fielded. Seemed to be an independent shrinking of bore diameter trend proceeding in several nations even as "smokeless powder" was under development in Franceicon.
