Definition:
Cordite N is used as a propellant in aircraft gun ammunition. It actually contains three main explosive components. These components are nitroguanidine, nitrocellulose, and nitroglycerin. Cordite N is very cool burning, with little smoke and no flash, and has no flash, and has a higher velocity or burning rate than Ballistite.

Now my question is how does that person know what cordite smells like?
Ex-military?
As someone mentioned up thread, if you've ever shot a gun, you've smelled cordite.
Now I'm hearing smoke smell and electrical smell. Nobody heard an explosion.
It was a fairly common powder used in firearms for many years. Many in the army would recognize it right off. Also, I think it might be used in fireworks.
There's a lot of ex-military in the UK. They'd know what cordite smells like - you never forget that smell.
