I am currently restoring the remains of a WWII Home Guard Northover Projector. There are plenty of websites with info about the weapon specs, projectiles, etc. but little about the weapon's origination. I am particularly trying to discover the origins of the name. Was Northover the name of the inventor? And the nearest date I have for the introduction is April/May 1940. When completed, the weapon will be displayed as part of living history/interpretation/museum diorama. So the information needs to be spot on.
