Notes:

The years 1967 to March 1974 (when Conn moved their brass manufacturing to Abilene, Texas), is a period where at least some of the instruments were inferior in quality

In March of 1974 an alpha-numeric system was established: The first character of the serial number indicated the decade;

• "G" for the 1970's,
• "H" for the 1980's, etc.

The second character indicated the month of the year;

• "A" for January,
• "B" for February,
• "C" for March, etc.

The third character indicated the year within the decade (defined by the first letter).

The fourth character indicated the instrument:

• "1" = Cornet,
• "2" = Trumpet,
• "3" = Alto Horn,
• "4" = French Horn,
• "5" = Mellophone,
• "6" = Valve Trombone,
• "7" = Slide Trombone,
• "8" = Baritone Horn & Euphonium,
• "9" = Tuba, and
• "10" = Sousaphone.

The remaining numbers indicated the production number within the month.

From 1987 on, the two-digit prefix number plus 50 will give you the year of manufacture.
