I have a similar model GE Range. Mine has no window on the large oven; does have the sensi temp burner ; doesn't have
the meat probe, but does have self cleaning large oven, though
it is not described as "P - 7", as that feature subsequently became known. The other visual difference is that all of the timer knobettes, oven control knobs, and temp control knobs
have white plastic, not black. The model number plate on mine
is rectangular aluminum held on by two small phillips head
screws between the storage drawers. The model number on mine appears to be "J 486 Y 1 W ". I don't know the year of production. If somebody knows GE's dating codes they may tell us.
