Kopp Red Warning Light Lens for Fire Truck, Ambulance, Police, Dietz Lamps

Description

This is a real solid lens, well made by Kopp in a nice deep ruby red color.  This is a "spot" type lens with no prisming.  The paper towel beneath the photo makes it appear that there is some prisming, but there is not.  It is a clear red spot lens.  This lens is a direct replacement for the standard 1930's and 40's Dietz Hose Bed Lamps and likely for many other manufacturers' warning lamps, as well.  The dimensions are: Diameter- 5-5/8 inches at outside edge and
5-1/4 inches at the inner edge of the face that shows through the bezel.  This is a real hard-to-find piece and is in very nice condition.
