This Camion Protegido Nash-Quad is by Panzer-Garage and has an SHQ British paratrooper as commander from the leftover box.
Again by Minairons a pair of Carros Blindados Bilbao Mod.32. They were mostly used by the blue- later grey- clad Guardia de Asalto. The figure comes from the Minairons T-26.
I'm sure that if IM remodels it's Trubia they will solve these problems.
Another IM model, and much better designed, the Schneider tank. I only added the home made rear stowage boxes and the Hotchkiss Mg's.
