I’ve been gifted a small, top loading kiln. The model is “Custom-Bilt” by Norbert W. Priess at 2000 So. Fillmore in Denver, Colorado. Model 150H, Max. 2300 degrees, V. 220 W. , 38 K, A. 16.4. I have been unable to find any information on this kiln. Can anyone provide any information or leads as to where I can learn anything about it?
