So I'm calling it now, this Castellax is a recast. The multicolour resin is the giveaway. I got it in trade, and some other models. I have no regrets. I'm not actively buying recasts or advocating it. But from eBay or the internet, well, you get what you get.
This model is in rough shape, so I've set about to remedy that. I did a little deconstruction work.
I'll do some filing, trimming, and greenstuff work to this model before I pin it back together and get it based.
Speaking of, I decided on a basic layout for the ZM board and the Mechanicum teams bases. I'll use thin card over plastic canvas, and use dressmakers pins for rivets.
