I don't normally cross over to this side of the house much, but I do like the occasional Armour build and I've been planning to do this one for ages.
My 1/72 (76) operational WWI tank collection so far. But it's missing one, namely the Schneider CA1 the first operational tank in WWI. (arguably I should have some of the other MKs of Heavy tanks too but they may come later, along with a possible K-wagon (they almost finished two prototypes)) but the lack of a Schneider is really a gaping hole in the set. And yes I know there are resin Schneiders out there, but I enjoy scratch building plus they are hard to get hold of and ferociously expensive.
Starting with a wooden core and skinning it with plastic sheet panels. I've the underside and the lower and front panels attached. The pieces are more glued to the core than each other.
