Well, drawing number 10548b is certainly for the Beaux cartridge, since this drawing is in the Italian language. I read enough Italian to understand most of it, but I cannot see any case-length measurement in that drawing, which for what I am after is critical. Wish we could see 10548 and 10548a, which I assume existed.
Peelen - the drawing I have is not from that series - it is number 10.137. If you meant that my cartridge is probably the one reflected on Drawing 10548, that could be. I would have to see that drawing to know. My ignorance of foreign languages caused me to overlook, thru not understanding it, the notation about the drawing 10548, that is on my drawing. Thank you for pointing it out to me, as it is, obviously, an important notation. I can handle a little Spanish and Italian, and a trifle bit of German, but French is a total mystery to me.
Kriss - the drawing you show is the same as mine, I believe, except for lacking the “Avec la permission du Gévelot-Paris.”
The Italian-language drawing did put one thought into my mind, and that is that perhaps the overall case length I measured from my 7.65 Gevelot-Beaux cartridge is not what would be measured from a loaded cartridge. Mine is an empty case, and I note on the drawing that the cartridge in question used a roll crimp at the mouth, which would shorten it somewhat, and that shorter length would be reflected in the measurements derived from a loaded cartridge. Now, I will just have to use my poor math skills to add up the various measurements and see if I can come up with a case-length measurement on the Italian-language drawing.
Edited to correct a typo only.
