Hi MMD Readers!  Looking carefully at my Ampico box labels, in some
of them I discovered very small numbers at the right lower corner,
like 3-24, 5-27, etc.

I suppose that these numbers are the issue dates (dates perforated?)
of the rolls; am I correct in the supposition?  Does anybody know
exactly what these numbers means?

 [ Correct: 3-24 means March 1924; usually this is the month of
 [ the catalog in which the piano roll product is first offered or
 [ announced.  This date could be many months (or years) after the
 [ artist recorded the music roll.  For example, in the late 1920s,
 [ Ampico and DeLuxe (Welte Licensee) re-issued rolls originally
 [ published many years before, but with the expression codes revised
 [ for better reproduction with the later player mechanisms (e.g.,
 [ Ampico B).  -- Robbie
