The "wrist lanyard" is authentic and relatively scarce since they were a non-issue item added as a personal preference and not all Swiss Lugers had them applied. Many have worn out or have been removed by "collectors" who didn't realize they were legitimate. If you go to the Member Gallery and do a search on Swiss Family, you will see that my Cross in Shield example has a very similar lanyard.
Actually the lanyard serves a dual purpose. The longer version, such as yours, can be used as an aid in steadying the piece during firing. However, I believe the primary purpose was as a pull strap to aid in extracting the Luger from the form-fitting holster
