I made this Battlewagon from the Genestealer Cult Rock Grinder and the Galvanic Servohauler . There are also various other Ork bitz, especially the gretchin from the Stompa kit as well as some other strange bitz from various sources. I will likely simply use this as a Battlewagon and drop the crane as a mek workshop at the start of the game. I might also try using this as a Lifta Wagon. Oops. Need to drill my barrel holes.
WAAGH! Drilteef is the great battle fleet of the infamous Doc Drillteef, Ork warlord and dentist.
