Vintage Silver Overlay Perfume Bottle Green

Up for bid is this vintage perfume bottle. It is not marked. It is green in color and has a decorative overlay . I don't know if this is a sterling silver overlay or not. The overlay is not thick, but a thin layer, probably painted on. The bottle is in good condition, some minor wear, but not bad. The bottle measures about 5 3/4" in height and about 1 1/2" across the base. Thanks for looking. Please look at my other items up for bid this week.
