Help Identifying Luger

[RANGER94]

Hello Everyone,
Sorry this is my first post, please be patient.

My buddy inherited this luger from his father. His dad was a forward observer with the 94 Infantry Division during WW2. His father, who spoke fluent German, received it when his unit took the city of Ludwigshafen around 21 - 24 March 1945. He actually receive it voluntarily from a German citizen baker, who feared due to Nazi propaganda, American retribution. The story that was given with the gun indicated it had belonged to a German officer in WWI.

My question is what does he have here, and what is the ballpark value? Holster & Magazine are original.
