Dating a neck seems to be the easiest way to verify the age of a guitar but whats all that other stuff mean? One of my luthier friends finally explained it to me.
The number before the year actually stands for model designation.
2= strat 1=Jaguar 3= tele etc. (this has changed over time)
The letter stands for the neck profile
A" is the narrowest, "B" is normal, and "C" is the widest. (this has changed over time)
