If your neck plate has a large scripted "F", it is considered to have been stamped between late 19 if it includes a number sequence starting from 100000 through 750000. Both "N" and "E" series instruments could potentially have been created in Japan.
Neck plate stamping was employed from 1954 to 1976 on all models.
Especially unique neck plate stamping includes those serial numbers that start with a "o" or "-" sign (1957 through 1958), stamping at the bottom of the neck plate (1959 through 1960), double stamping and overlapped stamping.
Fender Musical Instruments Corporation entered the picture in the 1950s, when the V. Squier Company began supplying Southern California inventor and businessman Leo Fender with strings for his unusual new electric guitars. Before the Fender Squier line of guitars was introduced in 1982, Fender was making lower priced guitars such as the Fender Lead series at its Fullerton, California plant.
Until the introduction of the Fender Squier series, Fender had never produced lower priced guitars based on its main Stratocaster and Telecaster models and had always used different model designs for its lower priced guitars.
The Precision Bass models, for example, had bridge plates that were marked from 100 to 2000 between 19. Again, these numbers are specific to the bridge plate, which could have been removed and installed on your guitar at some point, or stored a time before installation at the plant.
The range 100-400 was used specifically between the years of 19. Notice that there is also overlap in serial numbers between different years.It's likely that your bass can be given a birth 'range' rather than a date.Fender stamped its bridge plates and neck plates in the early years.Fender began negotiations with several Japanese musical instrument distributors and reached an agreement with Yamano Gakki and Kanda Shokai to establish Fender Japan.Yamano Gakki was known for once being part of Epiphone Japan.Whether the instrument was found at a yard sale or a museum, there are several signs that can confirm the authenticity of an instrument. Fender has grown substantially since its establishment in 1946.
