Early Christmas Luger from wife

[Ice]

My wife just couldn't wait for Christmas so she found this Interarms American Eagle Mauser for me. Its absolutely brand new in box with book, target and all accessories. Best of all it has the P08 grip instead of the Swiss style. The serial number is strange because I thought all the Mauser Lugers started with 10. or 11.. Its serial number is RG0893. Can somebody tell me about this model and maybe when it was made? This gift just blows me away. Now I'll have to find something for her since she likes Lugers too. Parabellum Christmas?
