Vintage flashing intersection-traffic light

Description

Vintage intersection traffic light. Once hung above intersection flashing 4 red lights. I believed it worked when taken down but i have never tested it. Has one craked lense but still all there and all bulbs are there. It appears to be 4 smaller lights attached to each other. I know very little about brand, manufacturer or age. Seems very old and heavy it is all metal and glass.Sold as is as i cannot guarentee it still works.
