Sorry Bert I do not know things about Mars. I have to say I am not interrested in nor am I an expert (far from that). Actually thanks to Alan I was just focused on Italeri Rorke's Drift. As I feared Italeri makes new things out of old stuff. The brick walls and the well and the sandbags are former sets (not to mention the figures)... But Yes we have 2 new beautyful buildings and I definitely want to get them.
