Their are no models for them, at least not for WW2. When hunting for French models remember that the uniform changes very little between the World Wars, just paint them Khaki green instead of horizon blue. The ones below come from Gripping Beast's Woodbine Design range.
Senegalese Section Pack
Gripping Beast do a rage 10 man section packs, generic WWI French bodies in campaign dress with separate head options. In addition to the Senegalese heads I selected they have six other options, many of which are relatively suitable for WWII. I had to cut down the rather chunky bases on the Senegalese for them to fit on the 20mm bases I use .
Senegalese with Coupe-coupe
There is a bit of a scale difference within the gripping beasts range. The one piece models are somewhat chubbier than their two-piece counterparts. Not enough to make a difference from more than a foot distance, but noticeable close up.
Warlord Games - Gripping Beast - Perry Miniatures
Warlord's French look surprisingly slight in this image. In general the three ranges are close enough in scale to serve in the same army, although I would hesitate in placing them in the same unit. The webbing on the French troops appears to change between the wars, packs remain in the mainly the same places with significant stylistic differences, the cut of the coat is practically identical.
Overall the Gripping Beast Tirailleurs fill and important place in any French player's army. The models had minimal flash which was easily removed, the two-part models fitted together nicely with a secure join. The thick, wide and chunky integral base is a minor nuisance given the overall quality.
My Score 4/5
For the sake of completeness I must add that there is another company that does two part WWI French in the same vein, The Forgotten & Glorious Company of Art, regrettably their Senegalese are somewhat caricatured (British understatement - Incredibly Racist).
