DE 502
So familiar! Ours, though, was a DG 502.
We had it from 1966 to 1981, all it ever needed was a new lint screen!
The one thing I disliked about it was the speckled blue drum without an interior light. We worked around that with a magnetic flashlight (electric torch for those reading on BBC).
It was fast, quiet, reliable, and the dryness control worked very well. The dryness sensors are in the drum vanes. Scrub them with warm-to-hot water, and a coarse terrycloth, one cloth for each vane.
Yeah, yeah....drum size to cabinet width, continuous gas pilot rusted the drum, but still one of the best dryers I have ever used.
