Long-Lived Model:
That model, with model-year trim variations, was made through much of the '60s and on up until 1971, the last year GE made a bottom-mount model for quite a while.
The icemaker setup was branded Ice 'n Easy. Family friends had this fridge in Coppertone, and the icemaker went from enormous convenience when new, to PITA years later, when truly automatic icemakers had become the norm. How quickly we become spoiled.
