Airfix / HaT Industrie WW1 French Infantry painted in khaki to represent WW2 troops.
The set itself (not these actual figures though) was one of the first sets of 20mm figures I had as a kid at primary school - and that was a long time ago now.
I always thought that the guy with the carrier pigeon looked like he was holding a half-eaten sandwich that he'd just taken out of his hamper.
The figures have a lot of useful poses, it's a pity about the rifles as they are very flimsy and thin without any real detail, but they still have a place for me on the wargame table.
