Interesting fridge. It looks like a '57, but it has the later type of swing-out shelves. I'm going to guess that it's a later model but frosts freely, which may explain the '57-ish exterior. I'd be OK with something like that, but with the opposite door swing. $450 is really steep though.
I have that same GE Fridge in pink, minus the foot pedal and swing out shelves. It's a 1960 model with slightly smaller cu/ft than the turquoise one...and not a frost proof.
