Astra Model 400 Spanish Pistol Value & Information

Question
WE have found a Astra Model 400 pistol.  It is chambered for 9mm or .38 ACP.  It was made in Spain and is still oporational.  If you can give us a value quess or atleast direct us to a person who can, then please to so.

Answer
It should actually be chambered in 9mm Largo, not regular 9mm although bore diameter is the same. I have been told that .38 super will work though I have never tried it in my gun and would advise against it. In good shape they run in the $250.-600. range. Thanks.
