they are not repros, its probably dress Bavarian Artillery Sabre with quillback made by WKC post 1883, second one should be too a bavarian sabre inspired by Austrian M1861 modell by same Maker WKC, the last one could be cavalry unit dress sabre, anyway it could be dated post 1920 too, under crossguard is visible the maker, the condition of the last one is the worser.
