It’s a nicely painted model but the inner rivet counter would have me say that Empress have put the taller 1921 pattern turret on a 1914 hull. The 1914 pattern turret is noticeably shallower. Same thing could be said for the First Corps version, if it comes to that. I suppose it came down to economy rather than poor research. One turret, one hull and just swap the wheels for wire or solid.
Either way, they both give a good impression of a RR armoured car.
