Initiator for 3" Mortar

[CINDERSII]

Something a little different I have an ICIANZ initiator charge for a complete 3" mortar round that I have (the round is inert guys) this is placed inside the tail and the charge bags clipped to the tail depending on the range required, the round is then dropped down the tube the F/P flap hits the rod at the bottom and that sets the whole thing going.
Not something you see every day and technically a cartridge so I can posses a live one like this on my cartridge collectors license.

Here are the Canadian examples in my collection.

Interesting post and follow-up. I would not have known what one was. Thank you.
