Taht could be anywhere from a 1955 to 1957 Kenmore (Frog-eye as we ll it) dryer. If it spent its whole life along the gulf coast, it's looking to be cosmetically in very good chape for its age. Looks like it's missing the little knob to adjust the temperature on the left side. I wonder if the little thing that displays in that tiny little windows is missing too, that would show what temperature you'd selected, warm, medium, high.
