Mim tele dating
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 Fender serial number decoder currently supports all documented MIA, MIJ, MIM, MIK and MII formats with the exception of Custom Shop, Relic and Reissue instruments.
Please note that fender serial numbers tend to overlap by at least a year, and thereby the date of your guitar can only be approximated.
The neck date simply refers to the date that the individual component was produced.
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.
But once again, due to the modular nature of Fender's production methods, and the fact that most serial numbers schemes are not sequential and usually overlap from between 2 to 4 years, (from the early days of Fender, through to the mid 1980s), dating by the serial number is not an exact science.
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.
