GE Double 27" Wall Oven
Some time between 1978 and 1988, these were great ovens, the top Self-Cleaning-Oven is much more efficient than the lower Non-SCO. In fact no oven built uses as little energy as the SCO and even the lower oven is more efficient than many gas or electric ovens built today.
And these are great baking ovens, and extremely reliable and easy to repair ovens if something does go wrong.
