Guitars are numbered chronologically with a number that indicates
the year and the number for that guitar within that year.
The serial number is an
embedded "wooden coin" on
the back of the guitar near the tail of the
instrument. The coin has two sections which indicate
the year of production and the number of the instrument in that
year. The first part is
the serial number which is a six digit number. The last
four numbers provide the number of the guitar for the production
year. The year of production is defined buy Roman Numerals
at the bottom of the emblem.
Serial Numbers that start
with "PRO-XX" indicate a numbered
prototype. The XX is the number of the prototype
for the described year, identified by Roman
Numerals at the bottom of the emblem.
