I can answer some of the questions here. I have been the caretaker of this horn for several years now on behalf of the buyer at the Guernsey auction. Now he has decided to offer it up for sale again by way of this auction. I find it unlikely it will sell at this time and if not, it probably will not be offered again for some years. Adjusted for inflation it is selling for about what it did in 2005 at what was a mammoth jazz auction.
My tech did the restoration on the horn a few years ago. During that time I've made it available for use to some of the great local players like Jerry Bergonzi and Alan Chase as well as a few serious players who passed through this area. All were in agreement that it was a phenomenal horn and the experience of playing it was quite special.
This was Dolphy's only alto for most of his career, purchased new in LA around 1949 and used by him exclusively until it went to Trane's nephew in Dec '63. For the last few months of his life Dolphy used a VI. He used this SBA while with Mingus, with Trane and on Blues and the Abstract Truth among others.
I had the great pleasure of playing this horn with Rakalam Bob Moses who, as a boy, sat in with MIngus, his neighbor, and played alongside Dolphy using the same horn.
Obviously for serious people and institutions in the jazz world, the horn holds some real value and historical significance. It has been my great honor to have it in my care...
