A group dedicated to the discussion, research and history of 1115 Mack buses acquired between 1935 and 1959 by the International Railway Company (IRC) and after 1950, by Niagara Frontier Transit(NFT). Before the war IRC was the largest purchaser of Mack buses and after the war NFT was the second largest purchaser of Mack buses.
