Luftwaffe 2nd dagger, are these parts genuine?

[Rob L]

Hi everyone. I'm getting together a 2nd type luftwaffe dagger out of parts and got the cross guard and pommel from Johnson's. These are so mint they're certainly unissued to a point are they genuine parts? I can't tell what they're made from, certainly not aluminium as I work in the metal industry, the're quite bright almost like chrome. Looking around at images I place the detail as F.W.Hollar, correct me if I'm wrong I'm very new to daggers. Any help to I.D and if they're genuine would be greatly appreciated, thanks. :-)
