Here is a very unusual bulb for your collection. It is in like new condition.
The tip is perfect and the glass is as clear as the day it was made.
It has the spring like tungsten filament, with hand written numbers on the stem that match what is shown on the perfect label. It shows this bulb to be, 56 watts, 115 volts. The label says: Edison Mazda – ST. RY. Headlight…meaning it was a headlight bulb made for the streetcar, railway vehicles that were used way back when. It also has the nice Edison GE Mazda etching in the glass on the other side.
What an unusual bulb!
