Pat, I have yet to convert the redbox figs, they are the closest to Madist gun crews yet, although not perfect, in the absence of better, they will have to do. The gun crews were often pressed men , ie captured Egyptian gunners who either wore plain white cloth or less common their old uniforms, adding chains may be beyond my conversion skills though
Not difficult--either a bit of ribbon epoxy around the ankles or thin strips of cardboard, connected by very fine chain from the model railroad shop.
