| The date is uncertin,,I would guess the first year or so,,The basses with the humps were a full 1 inch wider across the top on the upper part of the top(under the fingerboard),the neck design was changed ,but I did own #66 at one time and it did not have humps,,so they were making both early on.
I have taken over ownership of the Am Standard web page ,and in the process of updating it as we speak,,I hope to have it back up and running in a few weeks,,We will be updating it regulary,,so get your A/S,,and King's ready.Kent |
