The ones with the 2 labels have a date code as the 4 digit prefix on the S/N - so a unit that says "S/N 0416-756124" was made in week 16 2004. All the ones I've seen date from 2003 or 2004.
The board they were originally attached to was largely empty - although it did have a label indicating that the board name was "HSO" (presumably "high stability oscillator") and a part of serial number stickers in a format that instantly made me think "Motorola" (the P/N started with SGLA4000, IIRC).
