You can tell the insurance co. whatever you wish, or whatever you wish to pay premiums on. $1000 is a generous figure.
With no suffix on the mag. does anyone believe that the numbers are from original WW1 mfg. or later police adaptation?
Overall a nice quality Luger.

The mag is police marked with a '2'. If it were the original mag it would have the suffix and a '+' to indicate the spare or second mag.
