12 Gauge BIRD SCARE shell

This 12 gauge shell was given to me by a retired Saskatchewan Conservation Officer about 25 years ago. He said they were used to scare ducks & geese out of farmers crops where they were causing damage. They have a small powder charge that shoots the red cylinder inclosed out a few hundred yards where it explodes and scares the birds away. Does anyone have any info on this shell? Who is MH INC ? The primer is marked NOC.[/img]
