Schalburg Korp and perhaps something else?
There is an immediate association with Schalburg Korp, although some suggest Deutscher Pfadfinder and early NSDAP supporters. If my memory serves me correctly, I think that one of the reference books even has an image of an early SS man wearing a similar buckle!
I have seen this roundel set on different types of brass boxes, rather than a "common" style of box.
In addition, I have seen the roundel positioned in two ways. One with the swastika arms as vertical and horizontal and one, where the swastika arms are set at roughly 45 degrees. I wonder if there is some significance by this?
As always, any comments would be welcome.

David
