Snap on wrench

[Crashman]

Hi Guys,
I just bought an old XO series wrench. It doesn't have a date code on it. It says XO 1416 USA PAT 3273430. Can anyone tell me when it dates from? I looked on a few sites but could see it.
Thanks for your help.

Hi
this is my first post.
i have a C-106 Kit Bag with XO series combo box wrenches from circa 1970's.
one is missing, either the smallest or the largest.
the smallest one i have is XO1214, 3/8" - 7/16".
I will take a picture of it in the next day or so.
any info appreciated!
Brien
