My grandma's is from 1969, along w/ her fridge--and actually a 30"...
In fact, this stove seems a bit "no frills" compared to all the gadgets and extras that her timer dial was filled with--the inside was shiny and I wouldn't be surprised if it was a "pull-out oven", though she'd never demonstrated, just gave me the impression that it was OK to completely line the oven with foil, and replace ever so often (well, looking back, maybe she did)...
Her Kelvinator had no name-plate, either--so the serial plate w/ the Product of American Motors details gave me indication (or maybe the tag simply fell off) so the blank space on the control panel let me put my own Kelvinator badges there (just for them to be taken off & thrown out)--and my mom subliminally chastise me, going off to sleep, or just before waking not to put, or DRAW, as I had notoriously done, "Kelvinators" on grandma's stove; she could have been annoyed w/ my deadly practice, and the last-straw was an RCA Whirlpool lettering, from a discarded washer control panel that I'd played around with glued on... Recognizing a few cues of similarity to Whirlpool's that I had seen, I think I couldn't have been more accurate, whereas my mom's 1994 Tappan looked alike as far as the knob nomenclature goes, while the timer set up, just being the clock, minute timer & stop/start for the automatic timed-bake oven--and this was a DESIGNER SERIES by Tappan (Mont. Ward) my fav' stove that ma had, 'cept for it being as trouble-prone in oven calibration as her previous Tappan range (a double w/ upper microwave, that blew out) had been in its short life...
