From The Military Discipline wherein is Martially Showne the Order for Drilling the Musket and Pike, published by Thomas Jenner, London 1642. This is plate three of the drill book published just before the wars broke out. I’ve no reason to suspect this is anything other than portraits of the trained bandes of London at their postures. These guys are dressed in high status clothes, braided breeches and slashed sleeves. Not the kind of clobber you would wear to take the the field. Some fancy garters on display here too. This is number three in the series. I took the photos from the original book.
