There is an excellent guide on identifying exactly which mauser you have. The shoulder stock you have is definately German, not Chinese. Do some research, look for the serial numbers, including the one on the stock. If they all match the gun will be worth more than if they don't.
The inside of the grip panels are also serial numbered on the originals, and should match the gun. They probably don't, since your gun is marked 7.63 and panels are either from a war production run or a replacement.
Easiest way to discern an M30 from an earlier gun is to look for the step in the back of the grips. If it's there, it is NOT an M30 frame, but one of the earlier versions.
I just went through a rather long and complicated search for a pair of grips for an old pre-war c96 I'm rebuilding.
You'll get some info about the age of the gun if you run the serial numbers....but, you'll find out that the Orbendorf files were destroyed at the end of the war, and Mauser apparently did NOT run all their SN's sequentially.
Actual values will vary wildly, depending on what you have.
I recently bought a pre-war (not near as nice as yours appears to be) with matching numbers for 400 bucks.
A good collectable condition Mauser will bring around 2 grand, unless it is one of the rare versions, in which case it's worth as much as 9 to 10 grand.
Have you considered shooting it?
While not the most practical of hand guns, concealed carry might be problem, they are about the most fun you can have with your pants on.
A word of caution: There are a lot of different brands of ammo floating around out there whichare marked as and will chamber and fire through a 7.63 mauser, and contrary to what you might read on some web sites, these guns will NOT hold up well to hot loads. The surplus eastern bloc ammo that is currently being sold for the CZ was originally loaded for submachine guns and will turn a fine old c96 into semi-interesting paper-weight in short order.
And before anyone asks
yeah, I love these old hand cannons!!!
