Not necessarily…the Code Numbers ( both DWM and George Roth) indicate when the company started making them, and set the code in their Register…The cartridges having been made before DWM ( which existed as “DM” in the early 1890s…DWM was incorporated only in November 1896, and officially commenced trading under that banner in January 1897)
Also, another cartidge not listed in the “rimless” list is the 6,5x52 Italian (Carcano), which was already in existence for factory prototype rifles in 1890-91 ( M91 Rifles began production in 92-93.).
From original documentation, the course is Kommission 88 Patrone ( 7,9) 1888, followed by Belgian M89- 7,65 ( from a copy (in French) of the original contract, design and trials acceptance reports of 1889-90), followed by the M91 Carcano ( as an option to a rimmed case , of similar chamber design, as two alternates for Tender for an Italian Trials rifle ( Mauser supplied a couple of rifles for each type of cartridge)…and Mannlicher took the Italian Rimmed 6,5 and made it into the M1892 6,5x53R For Romania, but that’s another story…the Italians had set off the Licensing of Mannlicher’s Packet clip design with Steyr, which was used, Kommision 88 style, in the Carcano.
The 7x57 (Spanish) Mauser arose from the 1892-3 Trials for Spain ( Spain initially used some 7,65 Mauser 1891s for trials).
The only standout is the M1894 6,5 Swede,& Krag which seems to be a “black sheep” in this Mauser related family, because it is not directly derived from any of the preceding cartridges ( 88 and 89 are about .470 heads, the Italian/Romanians are .448- .450 heads ( disregarding the rim) whilst the Swede ( or Norwegian Krag) was .475 head…and the Krags were made by Steyr of Austria!!
Does anybody have any docs about the early design and development of the 6,5 M94 for Norway ( at the time co-partner in the Skandinavian Crown)… Mauser originally made a M93/94 trials carbine for Sweden in 8x58R Danish, patterned on the M92 trials for Spain, and the M90/91 Trials for Italy ( single column protruding mag, like the Belgain 89, Turk 90 and Argentine 91) But Sweden then had Mauser make a definitive M94 carbine in 6,5x55 Rimless, the Norwegian Krag cartridge…
What tortuous ways in the cartridge developmenmt world???
