I have a friend who has quite a few sets of these Proto wrenches. I am curious as to why they are painted yellow. I think they are 10 to 15 years old. Never been used.
WAG alert: Perhaps these were to be used around aircraft, and the color made it easier to keep from leaving one behind. I can find nothing to support that, nor anything else about these tools.

You might have something there. My friend's son was a sheet-metal worker on aircraft during Vietnam. I ll betcha that's where they came from.
