I'm not an expert but I'm under the impression that Japanese guitar makers weren't putting Fender-type headstocks on guitars until later in the '60s or early '70s. You might want to check out Teisco acoustics for which the dates are known and compare to yours. I don't recall whether they show acoustics in the ID section of Teisco Twangers but you might check there.
