We had an ANCIENT Frigidaire with those trays and they were my favorites. Fridge was so old it was all STEEL.
Dad to me & my brother, "Take that old fridge from the basement and move it into the nook on the patio."
Me and bro, "OK, Dad no sweat, shouldn't take more than 5 min."
Two of us go to pick up that thing to take it out the back door and almost pass out since it weighed at least 3X what we thought it should, based on our previous experiments with aluminum based fridges...
Father standing there laughing, "Uh, you might want to use the hand truck and cart it out via the garage door!"
