Clive,
As a collector of Canadian military equipment I would like to see specific items researched and documented like gas masks as well as other worthy items to cover.For a collector to have a reference book on what he collects is worth it's weight in gold when an item can be properly identified.I have in my Civil Defence collection a Mk VII gas mask bag that has Civil Defence Canada stencilled on the front.I also have a service respirator with A.R.P. stencilled on the cannister and would like to know more details of these items.
Dennis sounds like a good candidate to write that book.
Regards,Derk.
