I met this man today, and he said it was a roll-x incubator, but is was a 1 1/2 ft tall, and 2 ft wide, 2 ft long. The whole incubator is clear, and is completely acrylic. It uses one of the coil heating elements, and a bi-metal thermostat. He said that it hold three trays, and they all stack on each other, and tilt to turn the eggs, He didn't have the egg turner assembly, but he used it to keep chicks after they had hatched. I don't think I have seen anything like it before. It also has 2 large fans on the top side of the incubator blowing downward.
