Early bayonet ID?

Friend found a hoard of knives pre estate sale from a deceased relative. They said take the whole lot and it was about 500 various China replica swords, machetes, multi-tools, combat knives....90% Chinese made trinkets. I saved these 3 original looking bayonettes from a $100 valued pawn shop run. Any ine know what or when these were made? I'm thinking 1890-1930 as they have the balls on the ends of the metal scabbards..ones marked CSZ , ones AS FA , and one is German " Weyersberg". 2 are for same type as barrel ring and mount are same distance , other ring is closer to barrel and mount is deeper .
