I noticed this bad boy sitting up in a storage area of our shop and had to have it so they let me, ITT Model 13 100 watt mercury vapor @ 240 volts. A good cleaning, new photo control and lens and this puppy should be ready to shine.
The Series 13 was discontinued in 1989, right? Why did they make both models at the same time? Did they do the same with the 25 and 125? I've seen instructions sheets that served the 13, 113, 25, and 125.
