Help evaluate a Walter

[Svet]

Here is a German Walter PP with an aluminum corpus.
Pretty good condition (photos don't do the pistol justice).
I wonder what these lightened models (with aluminum corpus) are worth for.
Guess they were used by higher ranking officers. Might be wrong, of course.

Any info (especially pricing evaluation info) is welcome.

Thanks!

Your's should be in the Nazi commercial range. The C/N versions are harder to find.
As to who used it. Well, it was a commercial pistol and anyone with a permit to purchase could have bought it. A holster might lend a clue to who carried it.
The value here in the U.S., in that condition, I would say would be around $450 to $600.

Thanks a lot, r.blue.
Now I know what it is.
