I do not know that this happened nor am I arguing that it did, but would point out that Indians made heavy use of paints, body, clothing,weapons, and tools all are know to have been painted. Does this mean they painted own guns? I don’t know if a painted fusil is known as owned, and I can’t point to a painting that shows it, could it have happened? I wouldn’t kick a man with a painted gun out of my camp or ask them cover their gun.
