This short history of the Royal Small Arms Factory (RSAF) at Enfield Lock prepared by Miss Constance Mary Irons is just one of the many supplementary notes on the contributions made by individual research establishments and manufacturing branches during the First World War which were prepared by the Historical Records Branch but never included in the official History of the Ministry of Munitions when it was published in 1921. Nevertheless, it provides an important summary of the part played by one of the most important engineering establishments in Britain during the war, and is a significant addition to the history of the RSAF.

第一次世界大战期间皇家小型武器工厂的历史，恩菲尔德洛克，由 CM Irons 小姐在历史记录分部编写，1921 年 7 月 4 日 MUN 5/366

康斯坦斯·玛丽·艾恩斯小姐编写的恩菲尔德洛克皇家小型武器厂 (RSAF) 的简短历史只是第一次世界大战期间各个研究机构和制造部门所做贡献的众多补充说明之一，这些说明由历史记录科，但在 1921 年出版时从未被列入正式的军需部历史。然而，它提供了英国最重要的工程机构之一在战争期间所发挥的作用的重要总结，是对新加坡空军的历史意义重大。
