Hello again LU,
I have looked through Benders 'Luger Holsters' book and i cannot see these marks any where.
There is no maker code WwMg
and no E/hg10 mark.
If it is a military holster, which it must be as it is dated '41', it should have a WaA stamp and number.
The only thing i can think of, and this really is clutching at straws, is that it was made for some individual. (H.G.---surely not)
I must say that i do not think this would be the case for one minute.
Sorry i cannot be of more help........
Regards,
Steve.
