It is really interesting that Mannlichers designs are now what is considered weird and unique considering back in the day his ideas and designs really dominated for a while. Many different firearms were designed by him, and many used parts of his designs.
French
Berthiers,
Italian
Carcanos, German Commission 88 rifles, the M93, M95, and M96 turn-bolt Mannlichers in the 6.5x53r (used by the Netherlands, Romania, and Portugal). The more classic M1886, M1888, and M1888/90 action (Bulgaria, Siam, some South American countries, and of course Austria-Hungary). Then there is the M90/M95 action like what you have here (Bulgaria, Austria-Hungary,
Yugoslavia
,
Czechoslovakia
,
Hungary
, Austria, Nazi
Germany
). Even the Mannlicher-Schroder rifles which equipped Greece.
For a while there was some serious competation between Mauser and Mannlicher. After WWI Mauser won, but Mannlichers designs still put up quite a good fight, some still being adapted after his death (such as the M35 Hungarian Rifle). Too bad he had to die in 1904, I would have loved to have seen what else he would have come up with.
