It clearly is made to resemble a High Brass Shotgun Shell although there are no markings on it anywhere. All visible evidence suggests this is a production piece although I have never seen another one like it. There does not seem to be a makers mark or any indication what the country of origin is. It includes a nostalgic Edison style decorator bulb and of coarse the harp and finial are included. There is no shade included.
