Old gas dryers with pilot lights
A lot of the earliest gas dryers had electric ignition, but some also had a pilot light the location varied
from being up under the top to being down in the front, but they were accessible for the user to relight them, many early users of gas dryers were thrifty enough to turn off the pilots and relight them on laundry day.
Maytag was the last manufacturer to discontinue, constant burning pilot lights. California sort of forced them to do that as they were banned about the same time Maytag got rid of the small halo of heat dryers.
Most other US gas dryer manufacturers had models with and without electric ignition depending on the market, they were sold in price level, etc., some manufacturers, such as Norge and whirlpool built models with pilot lights that gas companies liked to sell because they knew once they got the gas dryer into the home, even if the homeowner did not use the dryer, they knew it would burn a certain amount of gas every month and every year Just because it was sitting there with the pilot burning.
