Nice vintage cobalt blue and white porcelain enamel industrial shop/gas station light fixture.  The light has a nice, unique style shade. It is marked HL5878 A Elliptalux, the manufacturer is Crouse & Hinds. There are minor scratches, scuffs, white haze and a few small chips around the edges with random rust specks. The white finish has some chips and rust specks and chips on the edges.  It is in good condition. The thick wire looks original with the large porcelain socket. The socket will need a reducer to use a standard size bulb. The light is untested. The top mount is made of cast aluminum and is adjustable. The light does include the mounting nut and bolt.  Please look over the pictures and ask questions when needed. Thanks for looking.
