The neck code on my 72 Jazz is pretty much non existent, however the name “krausfeldt” is clearly stamped on it. I did a google search and found the below information on him which ties in nicely with my neck being from 72. I wondered whether there is a database anywhere of these old fender guitar makers and neck finishers, I’ve seen a few lists which have been started but nothing that I think has captured everything.
“I am that Ken Krausfeldt, and I worked at Fender from 1964 to 1974. For the first several years I shaped and final-sanded guitar necks and some bodies. Because all work was inspected before finish or paint each shaper had to identify his work. In my case, and at different times, rubber name stamps or simply a number was used (for me, #8). And rarely, simple printing was used. Because we were paid "piece-work" rates for each completed item the fastest way of identification was the order of the day.
During my tenure there, and after I returned from Viet-Nam ('67-'69) I supervised virtually every production line in the factory, except painting: Guitars, Amplifiers, Rogers Drums, and Fender-Rhodes Pianos. I wound up as supervisor of quality control. I left to join BIC-Venturi Stereo Speaker Company as Quality Control Manager.”
