There is a perfectly serviceable range of WW1 German Asia
Corps figures produced by Brigade Games. However, all have been sculpted
wearing the peaked cap and when the brief arrived to paint up some troops
wearing a mixture of peaked caps and tropical helmets it was time to do some
Frankenstein headswaps and some greenstuff additions.
It might seem like excessive work, but doing this adds
some variety to those figures already commercially available. There are a
handful of command figures to come in due course.
