I wonder how many of those young boys got called up in the Hitler military
Youth service.?
Probably none, as they would have been in their 50's and 60's by the time that rolled around and employed in desperately needed, indispensable "defense" industry jobs!
they took young & old; they took them right off the production line figuring the war effort more important...much of their undoing.
Late in the war, they did take everybody, because the factories were often pretty well bombed out anyway, but in the early going, they needed all the production capacity that they could muster, so many trades were deferred.
However, the point I was making is that the pamphlet I was reading was circa 1895, and I think the photo is from the same era, such that the boys in the photo would have been way too old (50's & 60's) to get called up into the Hitler Youth, by the time that became a thing in the late 1930's!
Just sayin' is all.
