It didn't have a stamped number and date, it was a plate riveted to the box
Also it was only outside during summer in the Southwest, little rain if any
saw this on ebay, 3/8 long ratchet with snapon racing handle in extreme green

I bought my first set of new snapon wrenches in 1989. I was injured and pawned them. My best friend forgot to pay my interest and they are long gone, I am still buying but a lot more is used than new. Someday I will replace that set of OEXL wrenchs
