What is the finish, barrel length, and type of front sight?
Does it have oversize Target stocks that cover up the butt and frontstrap?
What type of box is it; 2-piece cardboard or a presentation case? If cardboard, is it original to the gun? If so, there should be a white box end label with the gun's model number, barrel length, and serial number written on it in pencil, and the gun's serial number may also be scrawled elsewhere on the box in grease pencil. IIRC the box should be dark blue for a gun with blued finish, or light grey to silver for a gun with nickel finish.
