Evaluating a Luger

[Baggs]

Hi all, new user here.
My Dad had bought a Luger in the mid 60's, he passed away in '07..and that was one of the guns my mother always wanted to keep.

But lately she's thinking of selling it, as she's getting on in years.

I'm unsure of what pictures/info I could post in order for you savvy Luger folks to give me a price range I should ask for the gun.

Would someone be so kind as to let me know?

Thanks,
Mike
