I've had this knife for a while - it was a gift from a family friend.
From what I have found online my best guess is that it's some kind of postwar similar to a 3rd model.
The sheath is missing the chape and says "Made in Germany" on the back of the belt loop. I don't think it's original to the knife.
The handle appears to have had a symbol (possibly crossed-keys?) but it's worn away or was never good enough to be clear in the first place.
I've tried to capture this in the second photo.
The nut on the pommel is secure and will not twist off - I think the tang is peened over.
I'd appreciate any opinions regarding what the knife is and any value it may have.
