Depends on whether this is a pistol or a rifle - Mauser designed and produced many guns. Also, what condition it's in.
The Mauser pistol was used by the detective in the movie The Cheap Detective. The Mauser was also used by Sherlock Holmes in the movie A Game of Shadows.
Mauser never made chromed pistols, so the chroming essentially ruins it as a collectible. It is likely worth $150-200.
Mauser was located in Oberndorf Germany.
No published sn data. 10-100 USD
765.00
50-300 or more depending on specifics
Will depend entirely on condition. Could be $50, or $250. Most will be in between.
The first production semi auto pistol was the Mauser c/96 "broomhandle" pistol.

It depends on exactly which model it is. I have a model 1934 Mauser 7.65 pocket pistol that is worth (according to "the book") about $500, however, there are some rare models that are worth much more, some well over $1000, if I remember correctly.
