Your nr.3 piece is a austrian Werndl M1870/73 bayonet, made by OEWG by Steyr and unit marked to 42 Landwehr Battalion or Regiment, best regards,Andy
Ps the nr.1 scabbard was upgraded by Germans, there is a Landsturm unit probably and the frog stud was changed and the surface was nikled, i believe it could be captured in 1870 Prussian Franco war
