Not sure, but I think this is from this movie, currently rating 7(-8) only.
Some boys in different Lederhosen. An older, blonde boy or teen boy in short buckskin Lederhosen with H-style suspenders, a younger boy in smooth finish or nappa Lederhosen (probably with suspenders as well). Also some other, young boys in Lederhosen and shorts.
Very interesting, but there are even better movies in Lederhosen. Color would also be better.
