Fallschirmjager Gravity Knife Parts-WW2 or Postwar

[tejanofig]

I picked these up at an estate sale. However I don't own one so I can't compare the spring and lock. The spring with the flat end is 51.1mm long. The one with the rectangle type end is 51.4mm long. All have a sheared looking pin. The question is are they WW2 or Post war?
Thanks all. This is my first time using the photo attachment so bear with me if I get it wrong.

Almost all are postwar springs for bundeswehr type IV gravity knife.

the two springs with nickled lever on top look like ww2 pieces but they are broken unfortunately.
