This is my understanding also. I recently purchased on is poor condition (case) but the razor is still good. Lots of pre-war Canadian techs seems to be floating around but I'm also looking for them so that could be a factor.
My grandfather had one while fighting in the second world War. I wish he still had it. That razor has definitely got some miles on it.
I find it funny how you find things when you aren't looking for them then as soon as you start they all disappear.
