Nah, it took 11 years after the fact to stumble upon that nonsense.

As a professional industrial/product designer for over 20 years, I have to say, that assertion is 100% false; utter nonsense. Furthermore, having read your other comments on this subject, I'm here to tell you--albeit 11 years late---not only can there be, and likely, multiple prototypes as part of the product design, development and testing process, there was quite likely a pre-production Jazz Bass sample or samples built exactly to the final specifications for actual production. Knowing of Leo Fender's famous frugality, absent a statement from a credible source, such as FMIC, it's plausible that a pre-production sample, made in late 1959, was sold at Manny's Music in NYC, if the sample was approved as worthy by Fender. //Flowers purchased his famous Lake Placid Blue over Fiesta Red Fender Jazz at Manny's, without dispute. The fact that famous 1959 Jazz prototype many of us have seen in photographs, validated by FMIC and recently list on Reverb for $180K, was VVT but actual production Jazz Basses between 1960 and '61, phasing out completely in '62, indicates WITH ABSOLUTE 100% CERTAINTY that there MUST have been OTHER pre-production prototype variants or a sample with concentric VTVT controls!
