This is a Hitlerjugend (HJ) / Deutsche Jugend (DJ) Diensthemd.
It is in mint condition and even still has the RZM Indanthren H.J Braun label attached.
Hard to find like this. Impossible to upgrade. Small size.
One button on the sleeve (slip on) not present, but it’s amatter of slipping one through and done, no damage, all regular buttons present and nicely attached.
