I recognize those handles. Our '75 Coldspot had them, and they were used on models starting a couple of years earlier. I'm pretty sure that's a repaint. Turquoise was no longer offered by the time that fridge was produced, and to my knowledge, the grille at the bottom was usually black or silver regardless of the exterior cabinet color.
These fridges were well made, run quietly, and cool well. I presume it's in proper working order, and if that's the case, it may have a lot more years of life in it that you think. It's a rare model and was well worth saving.
You might want to launch a new thread, as that's the best way to attract interest. There are those among the membership who sigh and roll their eyes at revived ancient threads (including myself), but then I have a thing for refrigerators ;-)
