the act was repealed in 1782, due to the efforts of the highland society of london. william wilson & sons of bannockburn became the foremost weaving manufacturer around 1770 as suppliers of tartan to the military. wilson corresponded with his agents in the highlands to get information and samples of cloth from the clan districts to enable him to reproduce "perfectly genuine patterns" and recorded over 200 setts by 1822, many of which were tentatively named. the cockburn collection of named samples made by william wilson & sons was put together between 1810 and 1820 and is now in the mitchell library in glasgow. at this time many setts were simply numbered, or given fanciful names such as the "robin hood" tartan, not associated with any specific clan.
