Okay. I finally talked to Jim Hamilton, the maker. We talked for about three hours. Great guy.
He had the body of one already done, just sitting there. He's going to build one for me for $5500. He will do everything I want: sign, date, write "SRV 30th Anniversary #01", and give me a signed certificate of authenticity. He sent me photos of the body, showing the grain in the curly maple. It should be spectacular.
He's going to send me an invoice detailing all this, and I'm going to send him a boilerplate contract basically reiterating what we talked about.
It turns out he's only made 52 of these over the last 30 years. The other ones that are on the market are total fakes. He just hasn't had the $50,000 for an attorney to sue his ex-partner, who's been churning out these fakes with cheap wood, plastic mother of pearl, and just general low quality.
