Antique Scent Bottle In Rectangular Hinged Brass Case

Very unsual scent bottle in a hinged brass case. This was previously silver plated but the silver plate has worn away over the years leaving a pretty shiny brass finish. You can still see a little of the silver plate in areas (see images). Case has a round button at the front and the lid springs open when it is pressed, revealing a little bottle inside. Mechanism appears to be in perfect condition. W:3.5 c D:2.1 x H:4.1cm
