These models were Fender models and not Squier models.They had Fender USA pickups installed and were made for the Japanese market only and not for export .Tokai was seriously considered to start building the first Japanese made Fenders but after a breakdown in negotiations, Fuji Gen Gakki was chosen instead .The first Squier series was launched on July/August 1982 and over time the Squier series has slowly evolved to include original model designs and production has moved from Japan to various other Asian countries such as Korea and China. Initial Squier JV series The first Fender Japan models introduced in May 1982, were the 19 series which were Fender Stratocaster models ST'57-115, ST'57-85, ST'57-65, ST'62-115, ST'62-85, ST'62-65 and the Precision Bass models PB'57-95, PB'57-70, PB'62-98, PB'62-75.I have a Squier Stratocaster since about 1991, it has the white body and the clear wooden handle.I have never found any other number than on the head of the handle. I found on Internet a person who sold an Squier Télécaster with a similar serial number and an identical year of purchase. it does not move forward me the more, the more one be able to read on certain sites the same type of thing which you posted : There were also Korean Squier serials with no serial number prefix and 6 or 7 numbers and the first number is the year.Fender were also losing sales in Japan to Japanese guitar brands such as Tōkai, Greco and Fernandes, and the establishment of Fender Japan would benefit Fender sales in Japan as well as overseas.Fender began negotiations with several Japanese musical instrument distributors and reached an agreement with Yamano Gakki and Kanda Shokai to establish Fender Japan.
The following info will also help you determine if its a Fender Sqier number.S/E: The S and E serial number prefix Korean Squiers are from the late 1980s/early 1990s. There were also Korean Squier serials with no serial number prefix and 6 or 7 numbers and the first number is the year. Chinese & Taiwanese Squiers YN: Y = Yako (Taiwan), N = Nineties (1990s), the first number following the serial number prefix is the year. CY: C = China, Y = Yako (Taiwan), the serial number prefix is followed by a 2 number year. CY serials are usually used on Crafted in China Squiers.S = Samick, E = Young serial numbers were used on Young Chang's Fenix brand guitars . Some Chinese made Gretsch guitars also have a CY serial number.The Japanese MIJ (Made in Japan) Squiers were made by Fuji Gen up to 1997 and the Japanese CIJ (Crafted in Japan) Squiers were made by Tokai and Dyna from 1997. Mexican Squiers MN: M = Mexico, N = Nineties (1990s), the first number following the serial number prefix is the year.For example"MN8" indicates that it was made at Ensenada, Mexico in 1998.
