I Must Say:
These swing-out shelves look like they were a huge improvement over the "turnaround" shelves offered for some years previous to this model. Having survived a '58 bottom-freezer Combination with the turnaround shelves, I remember the shelves as both blessing and extreme nuisance.
The blessing came when you wanted something buried in the back of the fridge; you just rotated the shelf out and there it was.
The nuisance came when you wanted something buried in the back of the fridge and rotated the shelf out, to find that someone had put something on it that was top-heavy, not properly covered, or tall enough to catch on the shelf above.
The resulting spill went through the grid of the shelf and all the way down to whatever was underneath it, and if you weren't quick enough, all the way down through every shelf. The cleanup could be mammoth, as it was on several occasions when my jock of a brother booby-trapped the shelves through carelessness.
It seemingly always happened when he was gone somewhere, so there was nothing to do but grab a sponge and get busy.
Sigh. These solid swing-out shelves would have prevented many an irksome afternoon.
