It's a derrivative of their "match all" dryer.  The clue to this is the flip-down cover that would flip-up over the control knob and start button as seen in the photo.  All the other ones I seen of this "ilk" had a more horizontal pitch of the console.   Can tell this model has 3 cycles--one may be auto dry.  The other two look like air only and timed dry.  Not sure if this is a soft heat model or not.  Gordon will probably be able to enlighten us on specific features given we have the model number. 

My Mom had this dryer from 1973-2010, it started out life as an electric dryer but I converted it to gas about 30 years ago, and my younger brother gave it to someone when I installed a new Cabrio gas steam dryer  two years ago.

This dryer had an electronic sensor auto dry cycle that included the 2 1/2 hour Wrinkle-Guard cycle. I think that it claimed to be a soft-heat dryer but by around 1970 Sears abandoned the true variable input soft-heat that they had started using around 1963. These SH dryers no longer had dual heating elements in the electric models and no modulating input in the gas models, so the SH name was really a farce by this time.
