Early 70S SQ Gas Dryer
These were heavily built dryers but not really great dryers, they were slow drying and prone to blower bearing problems, they were also a bear to work on.
The rust on the upper back was from the constant burning pilot light, the steel cabinet is actually much stronger than the SS drum but not as corrosion resistant, LOL.
The front grill inside the drum opening is installed upside down, they have the dryers light opening at the bottom.
