IM REALLY NOT SURE WHAT I HAVE HERE. FOUND IT IN A JUNK PILE AND RESTORED IT TO ITS CURRENT CONDITION. IT LOOKS LIKE A SUPERIOR OUTDOOR DISPLAY SIGN BUT I WOULD LIKE TO KNOW MORE ABOUT IT. SUPOSABLY FROM THE 50'S. HAS DUAL POINT MECHANICAL FLASHER. THIS SIGN IS ABOUT 8' 6" TALL THE CENTER IS 36" DIA AND THE WIDTH IS ABOUT 10". 160 FLASHING LIGHTS. THE OTHER SIDE HAS ORIGONAL LETTERING " AUTO TRUCK AND TRACTOR PARTS".
