Are you a stickler for correct scale when it comes to figures, Trev? I can't think of anything in G that hasn't already been mentioned (the Prehm ones are lovely!), but if you could use figures that were closer to Gauge 1 (1/32, or 54mm in Model Soldier scale terminology) then you might find something suitable in the various ranges of modern repro "retro style" toy soldiers? There are sure to be some bands there, though you might have to pass over the military marching bands and search deeper for some more static poses....
