With the exception of the color, that fridge is identical to the one we had when I was growing up. It was replaced in '71, but still working great (we were moving to a new house, and my dad bought a new Frigidaire in avocado green).
Only one bad "incident" with the '56. My sister, who was 13 at the time, decided to take on the task of defrosting the freezer. Well, she made the mistake of not waiting long enough for some of the frost to thaw, and went at it with a ice pick and hammer. She perforated the top of the freezer, and you could hear a hissing sound (I guess the freon escaping). She called my mom (who was in the hospital at that time being treated for cancer), and was crying quite hard over what had happened. In hearing this, my mom started to cry too and blame herself for not being there to get things like that accomplished, and that the responsibility shouldn't be put on my sisters' shoulders.
Long story short...my father called the local Frigidaire appliance service store, they came and picked the refrigerator up, and had it back to us in a few days with no problems whatsoever. It was somewhat weird to have the fridge contents in an Coleman ice chest sitting where the fridge was, and the freezer contents being stored in a neighbors freezer.
(And yes, Weed, I remember the plastic freezer "spatula" all too well. Doesn't it have "Frigidaire" (in blue lettering) on it?
