Klein and Sons nut drivers

[fourjeepin]

I found a set of Klein nut drivers while clearing out my step dads shed for my mom. I know the new ones have Klein embossed on the handle. Anyone know when the ones with Klein and Sons printed on the handle were last made?

I've snagged a few of the Klien's. But the rubber handle grips get in the way more than I'd like. I prefer acetate handles like old VACO's and Xcelite's.

According to an article at "Alloy Artifacts", that logo was used between 1950 and 1974.
