Cased Japanese Signal Lamp-This measures approx. 11 ½” long, by 9 ½” high, by 6 ½” deep. It is a beautifully constructed wooden case that has dovetail construction. There are a number of data plates along with a brown leather carrying handle. The interior has all of the correct components and fitted compartments, including extra lenses to change the colors. This is in very nice condition and certainly not a common item.
