Indeed, the figure of the "sans culotte" has, originally, a Phrygian hat at the end of the rifle. The ball which we sometimes see instead of the cap, is a defect of molding and not a bread or other. It is in fact a matter of lack of plastic.

On the picture of the carcass containing moulds (opposite), I put in red the road the plastic when it is injected and which forms the cluster. It spreads then up to figurines. It is possible that sometimes the plastic does not reach up to the end, in particular in a mould placed at the end of the carcass.
