Проверяю серийник 7 7920 по
https://www.gibson.com/en-US/support/serial-number-search1952-1960 Les Paul, Explorer, Flying V, and Futura reissues (since late 1992):
M YRRR or MYRRRR
M is the model year being reissued
Y is the production year
RRR(R) indicates the guitar's place production for that year. NOTE: This number includes all models for a particular reissue year - so, for example, a 1958 Reissue serial number may include '58 Reissue LP Standard and '58 Explorer production.
У меня получается такая расшифровка серийника
7 7920 is the 920rd 1957 reissue model produced in 2007.
7 может означать года 1997 or 2007 or 2017
Хотя в объявлении написано "
выпуск 2002 г.".
