Vintage Handmade Copper Tone Chain & Loop Bib Necklace, Length 13.5”

Vintage Handmade Copper Tone Chain & Loop Bib Necklace, Length 13.5” - Length w/out extension 13.5” - Extension length 2.75” - Bottom loop width 2” Such an unusual piece! I could not find an exact match and there is no stamp so I believe this necklace is handmade. Loops are of twisted metal & are sodden with a separation in each to make them removable. All jewelry is polished to the best of my ability but may benefit from a professional cleaning.
