I have 20+ man units of Tirailleurs Senegalais in 28mm from four manufacturers.
The Eureka are half-a-head smaller than the other three brands, but are nice castings, poses are good. That officer is easily the worst of all the poses, I pitched him.
The others are all the same height, but differ in 'heft'. The Reviresco are the slimmest, next are those cast by Askari, with the Castaway Arts Tirailleurs the beefiest.
I think my favorites may be the Reviresco, which are also great value. They have that almost undefinable 'lean and hungry' look to them, which is how I've always pictured Tirailleurs Senegalais in my imagination.
