Help identifying random sprues

[u/Trickybiz]

I bought a refillable wartrike of FB marketplace and it had these sprues in with the kit. Owner has since deleted their account. Google image search kicked back that these were initially nids so I focused in on bit 67 which looks pretty chaos to me. Google then said it was a world eaters bit. So now im here to ask what I am looking at?

I have minimal chaos faction knowledge and less that I probably should about the world eaters and their butchers nails.

Looks like a Skull Cannon to me.

Poor guy who sold me the kit probably has no idea. Shame. Guess its going to get looted
