Luger Presentation Box - Pictures

[NavyVet24]

I came in to possession of 2 nice Luger Presentation wooden presentation boxes. However, their barrel cutouts are for a longer barrel than my wife's inherited Luger. I.e., hers will not fit because of the front sight. Hers has what appears to be a 4" barrel. Or something close. These boxes look like they are for a barrel about 2 inches longer. Did the Artillery version or another have a longer barrel? These are fitted boxes with lined cutouts. Right now, trying to find out what barrel lengths were made. I will try to take pictures and post.
