Usually I do not dig older metal models of any kind, but these you can do a little converting to and they should paint up well being mostly all armor.
First up is a Big Mek conversion with a Kustom Force Field. This was made from the new Morkanaut kit, of which I need to get off my ass and build!
Nob with Kustom boss pole. Only the best for the boyz!
I had this old grotzooka thingy I bought online for some Killer Kans a while back. It actually fits pretty well on these.
A lot of the arm bitz are from Kromlech. They're da bomb.
