Buckle with iron loop and inlaid copper-alloy tongue

Bronze tongue of an iron buckle, length 2cm. A waisted bronze tongue with a cast wedge-shaped cell on the back set with a flat garnet, seemingly rather thick and set on gold foil deep down. This cell is flush with the back of the tongue, but has projecting from it at either side a bronze 'wing' on a lower plane: these are flat 1.5mm thick, and 5mm wide. On underside of cast cell is a bronze rolled hook containing remains of an iron spring coil.Originally, it seems, this bronze fitting was part of a rectangular iron buckle - there is much iron adhering to underside of tongue-tip and to back of cell. Possibly the buckle was originally bronze and broken - cut down - and remounted in this freakish way. The iron loop has not survived.
