When I first saw your picture of it it reminded me a
bit of early Iron Age (Hallstatt era)
jewelry. The semi-circular bits hanging down. But none of the rest of it made sense.
When you see the new photos it does look like a hinge
part. I struggled though to see how it could be attached to the chest as there are no holes. But perhaps it was fixed with staples at the thin
part by each of those semi-circular bits.
I have never seen a parallel though.
