WW2 Canadian ? Fire Association/First Aid? Mk II Helmet - GSW 1941

A GSW 1941 produced Mk I Helmet in white ARP/Civil Defence finish with painted SFA insignia. I'm not sure what that means but something Fire Assoc or perhaps First Aid? Chinstrap has MRS HARWOOD written on it. Large Canadian liner with proper domed screw and nut. Possibly wartime issue or 1950's Civil Defence reissue.
