The torso is from a rather unassuming Verlinden bust, of which I got two:
Head & sun helmet are from an old legionnaire bust by Jean Jacques Lance made for DreamCatcher, the long defunct Belgian figure manufacturer, of which I got two also and painted one in 2014:
That leaves me with two French heads and two busts to combine, once I've worked out the uniformologic possibilities! BTW the original Verlinden got it all wrong: the officer has a captain's triple piping on his kepi, but has a contre-epaulette on his right shoulder, whereas he ought to have a full epaulette on both shoulders! Got to get this off my chest!
