Panzerfaust ground dug parts

[Normandy]

I picked up what appears to be a ground dug tube and parts for
the warhead. Any opinions or information on these parts would be welcomed.
First the head (PF 30?) is missing the lower cone and both tails are
missing fins...







tube...definitely not like the PF 30 I have. Could it be for a 60 ?











By the looks of it, these may be leftover parts from a restoration or a planned resto.

Drawing of the warhead

Thank you Karkon, the information was very helpful.
One thing I found interesting is that someone glued the
warhead into to the tail section upside down. In the 3rd picture its clear that
the lower half of the warhead and the tube which slides into the tail section
are missing.
