1865 Company founded by Charles Churchill. Charles Churchill and Co began trading in 1865 as importers of engineering tools and is thought to have imported the first examples of Morse tapered twist drills, self-centring drill chucks (manufactured by Cushman) and hand-held micrometers into the UK. According to Floud, he imported agricultural implements and other non-engineering items at this time. In its early years the company traded from 28 Wilson Street, Finsbury: sales catalogues were published certainly between 1876 and 1882 stating this address.

1897 Public company. Charles Churchill & Co Ltd was put into voluntary liquidation to aid capital restructuring. This comprised an increase in authorised share capital to £50,000: £30,000 was fully subscribed, £10,000 allotted as goodwill for the old company and £10,000 retained for later issue.
Within two years the company advertised with contact addresses at 2 – 10 Albert Street in Birmingham, 5 Cross Street in Manchester and 52 Bothwell Street, Glasgow, and its main office at 9 – 15 Leonard Street, Finsbury.
The capital restructuring also saw the addition of Herbert Chamberlain, brother of Joseph Chamberlain, to the board of directors. He was well connected in business terms as well as politically, having interests in BSA among other things. Other members of the Chamberlain family were later involved in the company.
The new main office in Leonard Street opened around 1896 and comprised 12,474 square feet over four storeys, complete with internal hydraulic lifts, an external hydraulic crane and electric lighting; the company claimed in its press release that it had more than doubled its sales compared to any previous year and that it had sales lists for in excess of 100 US machinery manufacturers.
