Greco serial number dating
With "Greco", the information of production year and serial number stamped started from around 75.
Because serial numbers did not exist before, the production year is identified by the logo font and the parts.
System 1: 1975 - 1994, alphanumeric "7 digits".
EX - 1) "K773422" means:
K = production month ( A =January, B = February... K = November, L = December)
77 (next 2 digits) = production year (77 = 1977, 79 = 1979)
3422 (last 4 digits) production sequence.
System 2: Like below it consists "5 digits" inspired by Gibson S/N type from 1980. Relates to the "super real series" and after that to the"mint collection series".
EX - 2) "04236" means:
The first digit = production year (0 = 1980 or 1990, 2 = 1982 or1992)
4236 (last 4 digits) production sequence.
System 3: After 95, similar to system 1
