Marking on SA armband question

[German_military]

Hello,
I just got this SA armband. I'm pretty convinced that it was worn by the Hitler youth, since it came with a HJ grouping that wasn't in a collection before. Was that indeed done sometimes?

Can someone tell me what the markings mean, or can someone tell more about the age of this armband'?

The markings below SA der NSDAP are:

STAM 234
...

Thanks,
Frank

Definitely SA and not HJ (HJ wore the type with the central white stripe and the swastika in a diagonal square of white). The stamp is that of SA Standarte 234.
