v_lazy_dragon, thanks for the email nfo.
In Helion's "One King", the uniform info gives the foot guards pikemen *polished back and breast plates£, * white sashes", but is this just for parade or ceremonial wear?
Also,in Fighting for Liberty ", there is a picture of a pike man from the Queen Dowager's Regiment, (Kirke's), who has removed his armour and doesn't wear a sash.
None of the pikemen are described as wearing helmets.
