The Indian Motocycle Manufacturing Company – yes, spelled that way – of Springfield, Massachusetts, was America's oldest motorcycle brand and once the largest manufacturer of motorcycles in the world. There was the Scout, made prior to WWII, and the Chief, in production from 1922 to 1953. In 1914, Erwin "Cannonball" Baker rode an Indian across America, from San Diego to New York, in a record eleven days, twelve hours and ten minutes. Two years later he was riding the Powerplus, a side-valve V-Twin, and that was in production until 1924. This looks like one of those.
In 1945, a group headed by Ralph B. Rogers purchased controlling interest in the Indian company and things went downhill – Indian discontinued the Scout and began to manufacture lightweight motorcycles. Poor quality and a lack of development petty much ended things. Manufacture of all products was halted in 1953 – Brockhouse Engineering and Royal Enfield bikes were imported from England and sold as Indians through the rest of the fifties. The Indian name then passed to the company that imported Matchless motorcycles into the United States, but they didn't use the name, and they went into liquidation in 1962. No more Indians.
So it goes.
