Humber Cycles
There was a resurgence in domestic and export demand for pedal bicycles and by February 1932 Raleigh had acquired all the Humber Limited trade marks. Manufacture was transferred to Raleigh's Nottingham works.[20] Raleigh-made Humbers differed from Raleighs only in chainwheels, fork crowns and some brakework.
During World War II, the Raleigh factory in Nottingham was used for the production of fuzes. Bicycle production was reduced to approximately 5% of its peacetime capacity.
In 1939, Raleigh opened a bicycle factory at 6 Hanover Quay, Dublin, Ireland and commenced bicycle production there. The Raleigh (Ireland) business expanded and moved to 8–11 Hanover Quay, Dublin in 1943. The plant produced complete bicycles and Sturmey-Archer hubs, and remained in production until 1976, when the factory burned down. Models produced there latterly were the Chopper and Triumph 20. The head badges changed in the late 1960s, possibly after the passing of the Trade Descriptions Act in the UK. Dublin-made machines no longer had "Nottingham England" on the Heron or Triumph head badge, the panel being left blank instead.
