The recent for sale post has a
A nice example of 9.5mm M1887 (Black powder) Mauser
Cartridge, but by SMI 1928.
Now, knowing that Turkey in 1926-28 had ordered a lot of 7,9 from HP, and others, as it was converting its calibre and ammo factories to 7,9 from 7.65 and possibly 9.5, both used in WWI…and could not make their own 9.5mm, as these were supplied by Germany initially as loaded ammo and also components for filling in Turkey, they ordered from Italy to fill needs for the few M87s still in tertiary service.
The other possibility is that the Italian colonies of Tripolitania, Cyrenaica and Fezzan, ( “Libia”)
required supplies of ammo for the thousands of M87s captured during the 1911 Italo-Turkish war ( which gave Libia, the Dodecanese Islands and Rhodes to Italy from the Ottoman Empire.
General Graziani, in the 1920s, was conducting search and destroy missions against the Senussi rebels and in particular Ali Muktar ( eventually captured and hanged), and need to arm and equip the native gendarmerie with weapons of a secondary nature, in this case, the 87 Turk Mauser. The Vetterlis and the M95 Austrian rifles were going to Eritrea and Somalia.
Little info is available from our usual Italian Sources…but something maybe found??
A Packet label, or some official document? Or the SMI archives?
