Hi Craig,
Congratulations on a wonderful $ 1500 score. The Portuguese rig alone is worth over $350-400...so your Luger price is even better !
BTW...there is a M1906 AE discussion occuring over on Jan Still's gun boards...centered around whether the "germany' stamping on M1906's should or should not display the halo-effect (or maybe both conditions are correct and proper).

From the front-view photo of your Luger, it appears your gun has the halo along the "germany" stamping.
Could you take a closer look and confirm this ?
