Possible Frame for Inlays

"Bronze inlay with deep internal segmented hollows (for glass paste?),
in outline of aegis of Seth facing right, wearing Double Crown: interpreted by Petrie as a brand"
Period - New Kingdom (1350BCE-1550BCE)
Petrie Museum UC63715

It's hard to imagine how this piece might have been used. Perhaps there was a loop on the back for it to hang as a pendant. However, with no mention of such, it probably does not exist now. Absent of a loop and independant of a setting in which it could fit, Petrie thought possibly it was a 'brand'. Hmmmm-m-m-m.
