Westfield Manufacturing Company was a leader in the bicycle industry. Many of the bicycles sold by the Sears Roebuck and Co. were manufactured by Westfield (although not exclusively). Sears bicycles such as the famous 1935-8 Elgin Bluebird were made by Westfield. So was the 1934-36 Elgin Blackhawk and Falcon among many others. Columbia was the in-house brand name for the Westfield Manufacturing Company.
