Old Hangar itens

Hi everyone.
So while messing on my storage i came across with 3 very old itens that i believe it has no use anymore but i don't know if there's any colectors paying for that or if i'm still missing anything regarding them.

Energy Storage TT 24ped
Odenfield Ventricle System TT 17ped
Hydraulic Manifold TT 15ped

Regards

I know only of 1 entity buying them, which I sold all my parts to.
It's that tall blue machine in every service center.
It will instantly buy your parts!
