This new saxophone was designed in Gerhard J. Keilwerth's shop in Nauheim, Germany.
It carries the Toneking name; the famous JK model that inspired it.
However, unlike the original JK horns, this model is not made in-house.
Apparently Herr Keilwerth outsourced the production of these horns to Amati.

Production appears to have been from 2011 to 2017.
