Three HJ schoulderboard buttons for review

[Christophorus]

Hi,
For your consideration, these 3 HJ buttons.
From the front, they look normal but the backmarks seem to be different from the normal ones: no M5/...
Two buttons have a "55" code. Is there a meaning for you?
Likewise have you ever seen "PRIMA QUALITAT"?
And finally the sun logo (makermark?).
Any help would be much appreciated.

These all look original , however ; numbered HJ buttons are almost indistinguishable when compared to Heer ( German army ) numbered shoulderstrap buttons . Most HJ.DJ shoulderstrap buttons have an RZM mark on the undersides as well . Heer buttons will usually just have a makers code (not Rzm ) .

Thanks Jo, you reassured me.
I am still doubtful on the one only marked by a "A" which is not for Assmann and with no rzm.
