Historical information
The Kettle Drum Drenching Gun was invented and predominately used in the 1940s and 1950s.
The Drench Gun was likely used to drench sheep with carbon tetrachloride for internal parasite control. These guns were widely used in Australia. There were problems with the design of the kettle Drum Drench Gun, however, which contributed to its demise.
On hot days and/or if the sheep struggled while being drenched, some fluid would miss its intended target and go into the windpipe and onto the lungs of sheep, often with fatal results. At times nearly one-third of a flock could be found dead. Inexperienced operators, overdoses and weather were often blamed for the deaths when it was often the design of the Drench Gun itself.
