What's it worth guys

[KATOOM37]

Helping a neighbor who doesn't know guns very well. He wants to get an accurate value for this Luger his dad brought back from WWII. The holster is pretty worn and is dated 1939. There are two mags with it but neither match the gun or each other. Also, the pictures do not show it but there is no date on top of the reciever like most I have seen.

Any help is much appreciated.

I have more pictures in my album.
