I called my brother on this - he worked at Cain too, for longer than I did. He corrected me on two things -

(1) we were at "L" for the year code when we both quit in early January 1984, and J wasn't skipped, so if L was 1983, you could go up or down the alphabet and figure the year from there.

(2) Also, the months were labeled different for different years, even vs odd perhaps. A-M and N-Z or thereabouts were the two month groups, always ascending. So, AL or NL was a January, 1983 tube, depending on the month code group for 1983.

He also suggested I speak with Bernie - maybe I'll have more.

Cheers,
