The web style holster was still in the CanadianForces supply system until the mid 90s. Perhaps that was why they are uncommon on the collectors market. I have routinely seen the holster sell for more than the pistols.
I have always had pretty good luck with the wartime Canadian flares. They are sometimes found at the gun shows, usually in the $5 to $15 range. I had a number of US made 1" flares, and while they would fire off, they would not usually ignite.
