Fender neck code
Until 1962, the necks were manually dated.
Then they were stamped at the heel and the neck was given a code indicating which model it was intended for. This code is sometimes mistaken for a date. For example, I have a Telecaster that says "3 MRT 1973", so the number 3 does not refer to the day but to the type of neck.
CoronadoII NeckdateSome numbers were changed again from 1966 (see overview below).
From 1962 the width of the neck is indicated with a single letter. For most necks this was standard "B", only other sizes could be ordered on special request.
