It is very hard to judge from this photo.

Another one is this catch, again compare it with the one on Johns site

Hello Zepp and Ben ,
let us take a look on the ears .
From both show wiedmann buckle boxes the ears are very similar . But when you take a look on the B&N ears you must see , there are very different .
Also my shown Wiedmann has a other post sleeve as that from John T .
I'm searching for
special SA/NSKK/NSFK with maker marks

Again Markus, just a theory, the Heer buckles are different anyway, here are more pics for comparison
