These are very rare stencils of the Julius Keilwerth top of the line Toneking Exclusiv saxophone marketed in Europe at the time. They closely resemble the very famous Couf Superba I tenor saxophones that were sold by Herb Couf of Royal Oak, Michigan in the late 70s and early 80s, but have some significant keywork improvements (pivoting spatula and Selmer-like octave key) and, of course, the famous "Naked Lady" engraving (this one is particularly enhanced compared to the norm).
Like most of the flagship saxophones made by Keilwerth, these included:
This one has been well-played but is in excellent shape, virtually dent and ding free, with ~75% lacquer remaining. It has had a complete overhaul within the last year...all keywork snugged up, with Precision firm pads, and large, rivetless domed stainless steel resonators. It is in perfect condition. It will come in a nondescript but functional Protec rectangular case that fits it well.
I also have an extra neck from a Couf Superba saxophone that I will sell along with this for an extra $150
