I caught that on re-reading. A Navy marked Victory will fetch up to $1200 depending on condition, it is a highly desirable gun. Even if it is just a 5-screw M&P, he got a great deal, especially since it still has the original diamond magna stocks (probably numbered to the gun).
I cannot find another photo. On reflection, I think it was a Victory model. I know he got a decent thumb break holster with it.
I have seen Victory models, that is my best guess.
You can never take enough pictures.
