391 is the Altec identifier and the next number is the year and the last two are the week. Yours were made in 1965 and are very early. The date code on mine is 391016 and they were bought new in 1970 and have serial #4133 and #4144.

Thanks, I spoke with Gary @ Lazarus SpeakerWorks and he re-edumacted me
