Excellent website, how did I not know, bookmarked
Canada was a Mfg. of gas masks for the commonwealth not much change
from WW1 to near the end of WW2.
Veteran captain James Bond (rtd.) volunteer at Vimy house was the real expert,
he worked on gas warfare at Porton Downs in the UK after the war.
Lived in Ottawa. I have some pictures of his from a chat/interview.
Would you include ARP? I have a picture of Canada mfg gas masks from a Asbestos site. ARP is Air raid Precautions and also called Air Raid Patrol.
I have many papers issued for the CD and ARP. I would buy the book.
Referring to Peter (NBCD) he is considered a expert in research and gas warfare.
