(Ver. 2.3) The Epiphone serial number decoder currently supports
11 serial number formats from 25 factories. Vintage numbers
from 1932 to 1970 are now supported. Serial numbers from 70'
and 80's era Epiphone guitars made in Japan are not supported.
The reason for this is that there is no reliable documentation
from this time period. More information about this can be found
in the FAQ. Please post any comments, particularly bugs in the
user feedback section.
