WW1 Luger holster makers listed by city

[cirelaw]

Thank You Ed! I recently purchased 'Luger And Holsters And Accessories' and awesome but still had questions. I posted four basic designs. There were over a hundred makers! Were there detailed designs for each. I posted 4 different designs that I have. Were there other designs. I am aware there was a change in color from brown to black. Was there a patent for each design? Uniformity? Specifications or demands? How much were the makers paid and who did the inspections?
