Need help identifying this Luger

[coastalcutt]

I was given this Luger several years ago by the widow of it's previous owner. She believes her husband may have purchased it from a GI who 'liberated' it following WWII.

I know nearly nothing about the gun. It's in the same condition as when I received it and has not been disassembled or cleaned in that time. I have fired a couple dozen rounds with it and it has the clip that came with it (not shown in the attached images.)

I'm hoping you can help me to answer several questions about the Luger.

1. What is the overall provenance of the Luger? Do the parts match? What year was it made and by whom?

2. What condition is the gun in? It has what appears to be wear in the finish but no major scratches, rust or pitting.

3. What's the retail and insurance value of the gun?

Thanks in advance for your help and advice.
