That's....
....A JK 25. P*7 upper oven, conventional-clean lower oven. Very nice unit if you only have occasional needs for the second oven.
For folks who needed two ovens a lot, GE also made the JK 29, which had the P*7 feature on both the upper and lower ovens. Extremely nice unit, but GE didn't exactly give 'em away - they were pricey. They're kind of HTF now.
