You seem to be up pretty well on that pistol. They were made from 1910 until 1934, when the very similar Model 1934 came out, and were very popular. They were sold in the U.S. and thousands were brought back as souvenirs in two world wars, so they are very common. The designer was Josef Nickl, who worked for many years for Mauser and who later worked on the Czech Models 22, 24 and 27, all of which share many characteristics with the Mausers as well as with each other.
Unfortunately, the guns are rather fragile; the trigger and trigger bar springs are notorious for breaking, but Wolff makes them and you can get them from places like Gun Parts Corp. Firing pins also break and the gun should NEVER be dry fired; get or make some snap caps to use when letting the firing pin down. Many show grip damage, where people have tried to pry the grips off, as well as damage to the sideplate, also from prying.
I don't know of any source of dating information, but that serial number is fairly early. Also common is the Model 1914, which is the same gun in .32ACP (7.65mm Browning). AFAIK, neither pistol was ever formally adopted by any military service, but some, mostly the 7.65mm version, were purchased in small lots by various military and police organizations, or by German officers as personal weapons.
