S-K Stubby ratchet

[alton1911]

I got this little S-K ratchet awhile back. The new production units look so much like this one. I have heard that the two letters between the retainer clip ends can be used to date these, but I never found out how to read it. This one is marked “AC”.
Any help would be appreciated.





Thanks again

Good luck, S-K won't reveal the key to decoding those............We've tried.
