couple questions on vintage Kennedy roller boxes

[1982fxr]

I have a couple of red kennedy roller cabinets, they each have 3 drawers on bottom where there sometimes is just an open space, with the 2 fold out metal door covers.

when did they switch from the rounded corners to the current square corners on their boxes?

Also, one is approx 18" deep and the other about 20" deep, didn't write the exact measurements, but one is a couple inches deeper. Just wondering on the age...

Are there any stickers in the drawers with the serial numbers? It looks like a model 520. Why I am asking is that these boxes look like they are from the Kennedy Kits era. I know from at least 1976 on they are square cornered boxes. Those are the age of the set of boxes my dad has. He has a set he bought in the 80's from a machinist who was retiring, they are Kennedy Kits boxes. I would date those as from the 60's.

Back in the 70s Sam's sold a Kennedy set with 6 drawer chest and 3 drawer cabinet. It had the rounded front.
