 Eventually, D&J started to manufacture their own complete saxophones (without any Keilwerth involvement) before supplying them directly to German musical instrument retailers as well as the export market.Saxophones manufactured by Dörfler & Jörka for distribution direct to retailers featured their own key mechanisms which were very closely modelled on Keilwerth designs, though not completely identical.It is important to note that D&J saxophones are not Keilwerth "stencils", but rather are nearly identical copies of Keilwerths from the same era.
