Here is a photo taken from a 1938 book. These are Western cartridges in 8 mm Lebel captured by the Nationalists in the northern front (Santander).
According to the Recovery Manual cited elsewhere in this forum, the headstamp should be (WESTERN 1916). The bullet should be similar to the french “D” bullet, solid GM. And the bullet would have a marking at its base: U8, the 8 being inside the U.
Is this information correct, or else what kind of bullet the Western Lebel cartridge had?
