Vintage Solingen Original Bowie Knife

This is a Vintage Solingen Original Bowie Knife. This is made in germany and is marked 708W. This blade does have some wear and shows its age but there are no cracks or chips. The wood handle looks like walnut or some other nice wood. The sheath is black and green and also is damaged but still supports the blade which is 8 in long. Do you have any info on this knife ? Im wondering how old it is,any idea?
