And you're fortunate that the clock/time still functions.  I believe this function is necessary for the P7 feature to work.

I agree with your estimated date of manufacture; however, as I read the numbers on the Data Plate they do not agree with the information that GE provides in their table of date codes (link provided).  During the 60's GE's serial numbers went wack-o and can be difficult to pin down.  It is possible that the "E" in the Model Number (J349E) indicates 1969.  The 1972 GE catalog contains a footnote that in the second quarter of 1972 the cabinet design and the model numbers for the ranges would begin to transition to a newer design.  This range is the older design, so it's not likely that it was built after 1972.

Watch Ebay for Use and Care Guides.  I doubt that you will find one printed specifically for this range, but more likely it will cover a multitude of models.

I have it as an extra dishwasher in the basement and I call it the KenROAR, as it does.  Mine was from the 90s, it looks like yours and was too new to be involved in the recall.  It works fine but you might want to go outside while it is running.
