This is the kitbashed greenskin baggage wagon as featured in the Tilea Campaign Part 3 story: Interlude, The Greenskin Corsairs.
I didn’t take WIP pictures, but here at least you can see it at different angles. The greenskins are old plastics. The wagon a Tomb Kings chariot (presumably looted after a battle, or found abandoned, or stolen from some other greenskins, or … who am I kidding, there must be thousands of possible ways they might have obtained it!?) which they have ‘fixed up’ a bit.
Pulled by an orc and a goblin, with a snotling along for the ride. The loot looks interesting – I’d love to know what goodies are in the chest!
