The WW2 Canadian Mk2 Helmet Size 7 1/8 A.R.P. Police is a steel combat helmet manufactured during the Second World War for use by Canadian emergency services. This example features a standard Mk2 bowl design with a rolled edge and is size-marked 7 1/8. The Mk2 helmet was widely used across Commonwealth forces and civil defense organizations, including Air Raid Precautions (A.R.P.) Police. These helmets were distinguished from military-issued versions by their often lighter gauge steel and specific unit markings, in this case indicating A.R.P. Police service. The exterior typically bears a subdued or painted finish, sometimes with identifiers such as ‘A.R.P.’ stenciling or decals. The interior features a webbed liner and adjustable leather chinstrap for secure fit, with markings denoting size and sometimes manufacturer or date. These helmets played a role in protecting personnel during air raids and emergencies on the home front.
