Duplex (automobile)The Duplex was a Canadian automobile built by the United Iron Works Company, of Montreal in 1923.[1] The engine was an unconventional 4-cylinder two-stroke engine with two pistons per cylinder, which the makers claimed gave excellent fuel economy.[1] The Duplex had a 110-inch (2.8 m) wheelbase, and the proposed tourer was priced at CA$1750.[2] The prototype was displayed at the 1923 Montreal Show, but there was very little interest shown, and production never eventuated.[2] References
