Hello friends, I have just picked up this 1939 dated Wardens MKII helmet with a nice MKI 1939 dated liner. The best bit is that it appears to have a contemporary fitted gas curtain. The curtain itself has had a few repairs around the rim area, all of which were repaired from the inside. I am led to believe that these curtains were mainly worn for protection from burning embers rather than for their proper purpose of gas protection. I hope you MKII experts like this one and please correct me and inform me on any points you may have, sorry the pictures are not great, I will take some better one's when it arrives!! Leon.
