I have this German Gravity knife with a "59" date on the blade and has the Othello logo of Anton Wingen,Jr. of Solingen Germany. Knife measures 5.25" closed and 9" in open position. It functions perfectly with the blade dropping out of the handle with you flip open the trap door and depress the push button. Reverse the process to close it. Some light scuffs and scratches on the blade. Blade does wobble some in the open position as all gravity knives do. The trap door is spring loaded and snaps open and closed. Handles are black plastic with no damage. Swivel bail. You don't see many of these compared to the wooden handle ones for WW2 or the later green plastic ones. This is a very cool knife and guaranteed to please the new owner. $250. w/US shipping included.
