Thanks for checking! Seems like both changes where implemented at the same time.
This is a guess; if DWM started their numbering for the German army with 1, yours is the 10809 delivered from march 1909 (9999 + 810) out of the approximately 15000 made that year (think the estimate is a bit high, as it was not a full year of production).
Does anyone know when they implemented the design changes? ..and from wich serial number?
Too bad there are so few shooter grade Lugers over in Iceland.. Good luck in your search for the next luger
