Okay Nick, you have two options: HJ-Streifendienst (Hitler Youth MP) or general HJ. The HJ-Streifendienst was closely linked to the SS from 1938 and acted as a preferred recruitment pool so that is perhaps the more interesting of the two options but a standard non-specific HJ uniform would of course be the easier of the two to assemble.
Here's the setup for the Streifendienst option:
HJ-Streifendienst Kameradschaftsführer.
Minimum age 14 but more likely to have rank if your son portrays a 15 year-old.
Uniform: standard winter and summer HJ uniform. No helmet, no gas mask. These were worn but only by the HJ auxiliary fire-fighting units (Feuerwehrscharen). If you are placing your son in a 'desperate last days of the war' scenario then really anything goes but for a correct and standard HJ-Streifendienst uniform there would be no helmet and no gas mask.
Cloth insignia:
HJ-Streifendienst shoulder straps (black with white piping and embroidered Bann number also in white). For the Bann number you could take the number of the HJ Bann which covered the area containing the LAH barracks which would be 37. Strap button number should be '1'.
Red/white Kameradschaftsführer
lanyard.
HJ-Streifendienst Cufftitle (if you can't find one the uniform will still be correct for the period you are looking at because the regulations state that the cufftitle was not worn by Streifendienst members below the rank of Scharführer from December 1941). The cufftitle was sewn on to the left sleeve 3 to 4cm below the elbow. You see them worn lower than this however.
Your
standard bearer patch should be
this type. It was worn on the upper right sleeve.
There is a large range of additional cloth insignia which you could add if you wished but these would not be items specific to the HJ-Streifendienst. If you would like to add anything just let us know and we can give you some possibilities.
Metal insignia:
He will need the diamond-shaped
HJ membership badge. It was worn on the left breast pocket.
This type of
shooting badge. It was worn on the right breast pocket directly below the achievement (proficiency) badge.
The
achievement badge should be the
black or
bronze level.
There are other badges you could add - sports, day badges and we can suggest some if you'd like to add some but these are not absolutely necessary.
Paperwork:
I don't know if you guys go this far but he would have carried a special
HJ-Streifendienst ID card. I have the standardised template for the for the Streifendienst ID and can scan that.
If you have any questions fire away and we'll assist where we can.
