2" British Mortar, Smoke or Practice

True, every little bit helps but the delay made little sense anyway. If you weren't firing out of concealment the puff of smoke that came with every Shot was easier to follow than the thin smoke stream behind the projectile.
HC and it's products are considered chemical weapons here so the safety Fuze Idea is out

Again, making my point on the old smoke producing fillings being hazardous to health. Mind you at least its not Titanium Tetrachloride! That stuff is really unpleasant when you get a lungful of the smoke, (experience tells me so)!

Come to the Darkside. TiCl4 wasn't enough for them
They mixed Sulfur Trioxide (anhydrous Sulfuric acid??) with Chlorsulfuric acid, called it Nebelsäure (Fog acid) and are still hurting people 80 years on.

Makes having a live 2" HC at home look a bit like Kindergarten.
