Metal clarinets were popular amongst military band players because they were more durable and less susceptible to humidity and temperature change than wooden clarinets. However, a metal clarinet's tone was considered harsher than that of a wooden clarinet. The 'Barret action' was originally designed for oboes. This type of key system was named after the French oboist and instrument designer Apollon Barret. It aims to provide similar fingering for different octaves and make trilling and slurring easier. Like Boosey & Co., Hawkes and Son published music and produced instruments for the military. These two rivals merged in 1930 to form Boosey & Hawkes.
