So I recently came into possession of a box of original metal Kasrkin. I'm not really a fan of the usual Cadian heads so I thought I'd try my hand at the venerable old head swap. Metal is considerably harder to work with that plastic for obvious reasons but I think I managed to get the point across.
The heads are from good old Victoria Miniatures and I added the rebreather sections from Vic's backpacks.
Quite simple conversions, but I'm not that much of a fan of the usual Cadian look. If GW offered alternative IG heads and backpacks etc, they'd be onto a winner.
