Herr Merick, The right grip looks considerable different then the left...Also there is a pretty large piece of grip missing on the left in front of the grip screw.
As Ed indicates it's either matching$$$ or it's not$. Either way $800 is approaching a shooter price.
Impossible to give much of an analysis from the photo's provided. You must disassemble the pistol and look it over carefully. If you do not know how or for some other reason you cannot.. you will buy a pig in a poke.
Another couple of things..determine the calibur. It should be 9MM.
If you want this for a shooter..make sure it shoots. You do not want to be forced to become a Luger mechanic before you are ready.
The magazine in the pistol may match..it looks original. Do not use it to shoot with. Get a Mecgar. Save the original.
There have been reams written about this. Like Ed says..do a search. It's all here.
Good Luck!
