he is ESTONIAN note the skull is non typical he is not 12th SS for sure. Very young but to well dressed for late war period where the kids did front line duty so was thinking he was Eastern HJ maybe
I've seen other photos of small children in uniforms made for photographs and "play". This is also possible. I initially missed the sleeve shield and the collar tab does appear to to be the Estonian tab with the arm and sword.
now a days probably is reproduced but am only interested in the content of the pic , if it is a child's dress up uniform it certainly would look different but suspect it is a period pic.
I think it is an SS-Zögling from the eastern. Normally they did wear a specific
armband. Maybe the lad used the arm-shield instead. I do like the photo very
much, repro or not!
