Caged cordial glasses and tray. Vintage

I purchased this in the 70's from an import shop. there are no markings. all of the 6 glasses are present and undamaged. this is some kind of brass alloy or if it is Mexico made, it is alpaca silver which is mostly brass. it was stored away when we stopped drinking liqueurs and switched to wine only.. the tray is 8" wide and 10 1/2" long. the metal is 3" tall, the glass is 2" tall.
