Sherryl, you are right, here is the post: Training device
it is a pyrotechnical device for practice hand grenades. Practice hand grenades are blue in contrast to dark green of the live versions. They equal in size, weight and form. Your device is screwed into the (reusable) hand practice grenade. It gives you a bang and a little flash. The red part on the threaded end gets hit by a percussion piece. The “effect” comes out on the opposite, blue end. The rifeling helps to screw in that piece into the grenade.
HGRL stands for Handgranatenladung (= hand grenade charge)
