This is a Japanese “prototype” FRT-3 that was supposedly made from a Floyd’s lost wax tooling in Japan according to one person who contacted Floyd Rose with questions (more below) regarding this FRT-3 style. It features no Floyd logo, has thinner chrome-plated insert blocks, and features an extremely rare end-slanted sustain block. This is what one seller claimed about this proto style FRT-3 when asking the Floyd Rose marketing department:
“I called and was transferred to the President of Marketing and he asked me to send photo’s. He’s obviously a busy guy, so took a few weeks & he got back to me. The following is the main text/body of his reply and I will forward the actual e-mail in it’s entirety to the next owner:
Hi Mike Sorry for my delay as I have been very tied up..
After the review of the photos…
This was definitely made by Floyd. It’s not one of the original machined ones, however they are one of the ones made off of the lost wax tooling that he made. This tooling was sent to Japan later and they took over manufacture of this type of tremolo. But I can tell by the sanding marks Floyd made this one.
I hope this helps.
Thank you
Andy”
So, according this this person, this was made from lost wax tooling by Floyd Himself. That being said, none of this has been completely confirmed.
