Canadian MKII Helmet marked A.R.P. (Air Raid Precaution) in red paint. Worn condition. Additional Notes: The Air Raid Precautions (ARP) was an organization in the United Kingdom set up as an aid in the prelude to the Second World War dedicated to the protection of civilians from the danger of air-raids. It was created in 1924 as a response to the fears about the growing threat from the development of bomber aircraft. Many of the practices and ideals set forth by the ARP lived on beyond the War thorough Civil Defense during the Cold War and still exist today in civilian organizations in the United Kingdom and the United States.
