Dating a japanese fender
They have been placed at the top of the neck plate, on the front of the headstock, on the back of the headstock, and on the back of the neck near where the neck bolts onto the body.
They were stamped on the back vibrato cover plate (early '50s Strats), and on the bridge plate between the pickup and the saddles on some Telecasters.
So, obviously a neck date, while being helpful in providing a date range of production, it cannot be a definitive reference.
Unlike the auto industry which has specific model years for their products, most specifications for a given Fender instrument model, change little if any, through the lifetime of the model.
The following chart details the Fender serial number schemes used from 1965 to 1976.
Given the modular nature of Fender's production techniques, an individual neck may have been produced in a given year, placed in the manufacturing warehouse and remained in stock for a period of time, and then subsequently paired with a body to create a complete guitar in the following year.There were periods of time when this was not consistently done, (between 19), and there are certainly other examples of short periods of time, and individual pieces, where the dating was simply omitted.While this neck dating is useful in roughly determining the age of a guitar, it is certainly not definitive.The JV and SQ guitars, as well as some of the E series, had USA parts (mostly pickups, switches, and potentiometers) that were shipped over to Japan to help speed up production while the new USA plant was being set up in Corona, California.The early series are the most popular for collectors.
