From Wikipedia: ""The Army & Navy Co-operative Society Ltd. was incorporated on 15 September 1871, being formed by a group of army and navy officers. The aim of the military co-operative was to supply goods to its members at the lowest remunerative rates, and was based on two earlier models – the Civil Service Supply Association and the Civil Service Co-operative Society.^[5] The society leased part of a distillery premises in Victoria Street, London which was owned by Vickers & Co, and by February 1872 a store for the sale of groceries was opened on the site.""
