I received my 12 IB's last week Thursday, Well there were only 11, but who's counting.
As Nick said they are all based on four poses, but different enough for variation.
Some simply have different heads, others have rolled up blankets and such added to the 'basic' figure.
It's really a random mix since I got 4 of the same pose variant and only one and two from another.
The LMG (Chauchat) man is simply an additional pose of the advacing figure.
Quality is quite good although not in the same league as Anglian, but then few figures are.
They do match Anglian in size however and the figures can easily be used in the same unit.
Faces are quite nice.
All , except the LMG man of course, are armed with the Moisin Nagant rifle. Looks a bit short IMHO, more like a carbine, but still reasonable.
If you want me to I'll take a picture of the set I received (unpainted still alas)
