Back in the late 1940's, I was about 9 years old, my family was living in this same old house with this same water heater. It was struck by lightning, which melted the insulation. My father went to Portland, probably to the Fowler factory, and got replacement insulation. Possibly new elements too, I don't remember. Or he may have gone to George Morlan, The Water Heater King. Anyway, he rebuilt it and it's still going strong. No leaks yet!
