The last of the company's designs to be built was the Viking I. The tailplane stabiliser and front-mounted tractor propeller had by now become established as the conventional layout, while an increasing number of manufacturers were hedging their bets by building both monoplanes and biplanes. The Viking I emerged as a conventional tractor biplane. The Viking failed to sell. Due to the lack of any commercial prospects, the company was wound up in April 1912, most of its assets being acquired by Handley Page.
