Here is a very nice Vintage Antique Made by The Cincinnati Victor Co., Large 9-1/2"" Diameter Steel Carbide Spot Search Head Light in Excellent Condition.  Outside diameter is 9-1/2" and the inside glass diameter is 7-1/2".  This may have been a maritime boat search spotlight, or an automotive light or Firetruck light, not sure.  It is very cool though and made of all steel.  The only thing it needs is a reflector there is not one in it.  Has 4 holes in the back side that must have been used to mount the reflector.  Comes with the bracketing shown and the base, swivels and tilts.  This is a very RARE light to find and in beautiful condition.  Any questions, please email.  Check out all the shipping options to get the best price.
