Gustav, Genschow Co. (GECO)

[mansolingen]

This knife was made by the Genschow Co. in Solingen Germany. I know he was a distributer of many products, mostly ammunition, but have seen a few blades with his name on them. No one seems to know anything about the age or markings on these knifes. I believe his name is Gustav. Ppl say they rarely see this mark on a blade. Have seen a few on a dagger, but seem to be rare. Fire arms and police weapons seems to be more popular. Any help or info would be appreciated.
