Vintage Gold-Tone 5 Row Brick Chain Link Bracelet 🤎

Vintage Gold-Tone Metal 5 row brick chain link bracelet Unique fastener that is embedded in the bracelet once in place. (Took me a minute to figure it out.) Classic. Simple. Beautiful. 7 1/2" length About 1" width No brand indicated. LSM is stamped on one link on inside of bracelet. 9th/10th pictures: Model in picture has 6 1/2" wrist and bracelet fits just loosely enough to slide a little. In like new condition. There may be very tiny scratches on outside of bracelet but it is so shiny it is hard to see. No flaws otherwise. I see no places where any of gold finish has rubbed off. Not sure what source metal is.
