I  WAS TOLD THAT THIS IS A OIL PRESSURE GAUGE FROM A 1918 DODGE, PART # 955-N. IT COULD POSSIBLY BE USED ON OTHER MAKES OF CARS. IT APPEARS TO BE IN GOOD CONDITION, BUT I HAVE NO WAY OF TESTING IT.  THERE ARE NO CRACKS ON THE GLASS LENS AND THE CHROME RIM COULD USE SOME CLEANING.  THE GAUGE WAS MADE BY THE NATIONAL GUAGE AND EQUIPMENT COMPANY, LACROSSE WISCONSIN. GOOD LUCK BIDDING!!!!
