I have acquired a 3/8" S-K ratchet wrench, Frankenstein push thru button type.
Took it apart to clean it up.
Under the C clip is AL.
This must be a date code.
There are no numbers on the handle. Just S-K logo early version inside a diamond.
Also USA next to this logo.
No numbers, so it is an early made S-K.
36 tooth count.
Superb shape, like new.
I would like to know how old?
Photos to follow if needed, but hoping a list of mfg codes is out there.
