Hamilton Electric Dryer
While Hamilton certainly pioneered Gas Dryers they made electric ones all along, we have seen and had many Hamilton electric dryers including one that was built before WW-2, [ the oldest home dryer I had ever seen ].
There is generally not much speed difference between gas and electric dryers of the same design except for the few makers that made extra high BTU or high wattage models that could really speed things up.
Early gas dryers were overwhelmingly electric ignition designs, We have this style Hamilton Dryer in gas with electric ignition at the museum. All MT GDs were electric ignition till the HOH design came out, also nearly all WP-KM, Norge, Easy, Blackstone and ABC-Kelvnator gas dryers were electric ignition, it really wasn't till the mid 50s on that some makers started making gas dryers with constant burning pilot at the urging of gas companies so they could sell more gas once they convinced reluctant housewives to buy a dryer. That way once the dryer was in the home they were guaranteed constant gas sales even if she still hung the clothing outside, LOL.
WP-KM gas dryers were nearly all electric ignition from the start through the present, only a few cheap low end models ever had constant burning pilot lights. MT was the last holdout in converting to electric ignition, MT didn't convert till 1976 when California banned the sale of dryers and gas ranges with constant burning pilot lights, it would be interesting to figure out the billions of cubic feet of gas California saved Californians and Americans overall with this simple regulation, this is a great example of the Government working for the general good of all people.
