rickn54 was the seller. Not sure if he stocks these, I really doubt it from his other listings. As it turned out the seller was a pawn shop.
The gun was sold as NIB and doesn't appear to have been fired as far as I can tell. It did have 2 very small black marks on it, 1 on the grip and another on the slide near the end. I haven't cleaned the gun yet so both may very well come right off in cleaning. I suspect it was from shipping in the Walther case.
I was open to either a SW or a Walther, was just waiting for the right deal to present itself. I had already seen a SW99c for $460 so when I saw the Walther for the same price it was a no brainer.
