~Need some form of imperial tank~

Hey guys, I need an imperial tank(s), any kind really for a modelling project.

Unpainted and unprimed would be best!

things this covers:
leman russ
chimera
Taurox
wyverns (hydras, basilisks, you know the type)
hellhound variants
anything FW would be great.

Basically anything non-marine, human, and roughly-ish the size of a leman russ or chimera

trade or cash!
