IDK, it's an original #140 Easton Posi

Ok - I think you decoded the B 1 G correctly. Not sure on the other.

Verified G is for 1966 from an original 67 Z28.

Do we know wether “H” or “I” was used for 1968? Mike mentioned that he was not sure if “I” was skipped it the alphabet. Thank you in advance for any clarification!

Based on post #12 and the photo there of a 1968 unit it looks like ... I....was used. Often times with dates and castings it is not, that is why I said I was not sure.

I'm going to bring this up again. I've got a 12 bolt 2 series Eaton Posi with a code that looks like A 6 70, but could be A 6 7C. Did they change from a letter code to a number code for the year in '70?

Thank you SSL78.

That shows I was used for both the month and year.

I’m bringing this thread back to the top because I need help with a date stamp. It looks to be D 3 D, which would be April 3, but I’m not able to figure out the year.
