Steve,
The grips are proper for a Swiss M1906 W+F Bern luger (aka M1906/24 or just M1924).
There are some more recent repros like the Bern grips...made in Italy but the border is not as wide.
The finish on the luger in the holster photo is quite not right...
If you switch to the Swiss luger section, looks for Bill Lyon's photos of his nice M1906/24 Bern luger. You can see Bern grips close up.
Regards,
Pete...
