I picked this up at auction yesterday. Sadly not cheap but does contain some items I have not seen before. The Brassard is dated 1940 as is the mask, bag and strap. Ointment tin has all its contents as does the anti gas goggles box. Anti Dim tube is dated 1939. The Gas detector paper is undated but also unused. The helmet was tied to the bag and it is dated 1939.
