The Fort Wayne & Wabash Valley Traction Company used a swastika within a circle on at least some of its electric coach cars... and this was back before a certain Austrian corporal showed up in Munich to paint postcards.
The Swastika was such a common symbol in American Indian culture that it was on the shoulder patch of the US 45th Infantry Division, which was the Oklahoma National Guard. They changed to a Thunderbird when the Swastika became known as the Nazi symbol.
