Hines Brothers are a firm of armourers who used to make crossbows and other weapons in Ankh-Morpork. Among their customers were the Watch. They were still in business at the time of Night Watch, but John Keel's special insight into the future revealed that in five years time, the firm of Burleigh and Stronginthearm would be setting up to offer competition. According to The Complete Ankh-Morpork Hines are still in business, offering bespoke weaponry, panel beating and rust proofing. They are currently located near the Barbican on the Street of Small Gods.
