I posted these on "The Hamb" today. A member was showing his gold pens his father got from an olds dealer he worked at and it reminded me of these.
We got them 45 YEARS ago and it still works fine. We mechanics were awarded them for going to Chrysler sponsored mechanics classes. I got this 1/4 set, a 3/8 inch drive set, A spark plug set, and a torques wrench over the years all in gold with nice black plastic cases embossed with the Chrysler logo.
They looked good but after awhile I just started using them on the job and still do as you can see by the crud on the handle.
If you look closely you can still see some of the gold in the lettering and handle.
