Pre 1964 Puma Waidmesser (Model 3591)

I have for sale a Pre 1964 Puma Waidmesser (Model 3591) for sale.    
The Waidmesser was part of a series developed in the 1950s by Puma-Werk in Solingen, Germany, in collaboration with Walter Frevert, a legendary German Chief Forester and hunting author. The knife is in perfect structural condition and everything is super tight. As you can see from the photos the blade has some scratches though. This is a highly collectible knife. I am asking $425 OBO.
