I would like to note that in the first and second pictures there is a difference in the metal fittings on the sheaths.

The sheath with the notched metal fitting is the same as the 1930 Puma catalog.

The sheath for the deer foot Puma does not have the notch and maybe be a later variation or a replacement sheath.

I have seen pictures of a group of four Nickers and the Weidmannsheil sheath was on the wrong Nicker, and not on the Weidmannsheil Nicker.
