This Keilwerth saxophone genealogy chart tracks how the Graslitz horns evolved, became the saxophones that were produced in Nauheim, and ultimately how they turned into the modern horns we can buy from the company today.

Note: Not all horns were stamped with their model numbers (Modell), and not all features were available in all voices of horns. This is a broad-strokes chart to show evolution, not necessarily horn-specific features.
*I have found no evidence from any sources that the Modell V exists, yet it clearly does.
