You are looking at a very cool, old explosion proof light fixture. The glass globe is marked Crouse Hinds VDB 3 and the old metal fixture is marked Signco Electric Kenilworth, N.J. The globe measures about six inches in diameter and overall the globe and fixture is a bit over ten inches tall. Really an unusual shaped glass. This would look great in any collection. I think this would work great as a design feature in or outside any contemporary home! Imagine this in your game room or home bar area...great conversation piece! When I picked this up years ago, the estate sale also had alot of railroad fixtures and the previous owner worked for one of them, in one of the yards. He had oil lamps and hooks and many different kinds of lights and signals, apparently liberated from work. T was a lot of stuff. This is one of the last items I have to sell from that sale. Good luck bidding and ask any questions.
