Universal - Cribben & Sexton Stove

I have a Universal - Cribben & Sexton stove that was left in the garage when bought the house. We were told that the previous owners were very into cooking.

 The plate under the back right burner say's:

In-A-Drawer Universal Flush to Wall Cribben & Sexton

9370  A 91743

22,000   12,000

22,000    12,000

Natural Gas

It has 4 burners and a large lid in the center and under it is a griddle which can be removed and has a grate that can be put on it to turn it into a larger burner. It has dual ovens and broilers on it. It is missing one knob but overall if very good condition. There is no grease under the cook top or in any of the ovens or broilers. The griddle does not even look like it was cooked on. Can't find out any information on the stove looking for some help and price on it.

Good
