four.cycle and Oldtuleguy,
Thanks for your great help!
The box I saw did not have any embossing and was too dirty to see if there were any decals left. However, everything you have posted sure makes it seem like the box at the thrift store was a Packer Auto Specialty or Ray. The ratchet in the other part of the store did not have Ray on it, and was black oxide - but it might have been from somewhere else and not part of the socket box.
It will be interesting to see what happens with the e-bay set in post # 7.
Appreciate the education. I know almost nothing about stamped sockets.
Thanks guys!
