They're stamped in the rear housing:
Auto Lamp Mfg Co
Model - 15
Chicago, U.S.A.
They're sealed beam with GE lamps, 6 V., one good, one burned out. One has the two interior spring clips missing but the inner lens holding ring is there. They're about 3 1/4" deep and 5" in diameter.
What tractor, I presume tractor, did they come on. Are they worth much?
