Here is another French binocular, a BBT Krauss 6x24, from the 1940's, when Paris was occupied by the Nazis. It came equipped with a reticle for the left telescope, which has disappeared. Underneath the left focussing ring is another ring, le micromètre orinentable, a way of rotating the reticle so it might be horizontal, no matter the IPD. By the late 1930's the French Army had moved to 8x30, as its standard binocular, so it was obsolete for the French. You may note that underneath the word "Décigrades," which has been lightly scored, on the left hand prism, "H/6400" was engraved, which is typical of the German Army. I suspect that basing a reticle on 6400 was easier than on 6280 milligradians, but that does not mean that a French reticle was actually replaced. On the right prism plate there is an engraving of a white circle, an indication of which lubricant was required.
So this binocular was either seized by the Germans and modified or contracted by the Germans in occupied France. As the Wehrmacht standard binocular was the 6x30, I surmise that it was supposed to be supplied to other Axis forces, probably fighting on the Russian front: Spanish, Italian, Bulgarian, etc., or units raised in German occupied territories like Denmark and the Netherlands. I purchased the binocular from the UK, so I have doubts that it actually reached Axis forces. Sometimes binoculars raise questions which may never be answered.
The contemporary Kern 6x24, made for the Swiss Army, has a larger FOV and is heavier and therefore feels better constructed. However, I think the BBT Krauss might still be useful for travel as it is relatively small and light. Of course, it is uncoated.
