I stumbled on these while browsing the 1946 edition (4th printing 1953) of the
NRA Book Of Small Arms, Volume 1, Pistols and Revolvers. I don't present it as the definitive description of these cartridges but as what shooters/reloaders had as reference material in those times.
There are many other cartridges shown; I posted these because they are the Luger cartridges.
Dimensions may not agree with other published (or believed) descriptions, but it's what the NRA writers observed prior and during 1946.
