The restoration of a WW2 40mm Mk 1 Anti-Aircraft field gun is taking place in the Parachute loft. Permission to visit this work in progress must be obtained and guided by a staff member.
The Bofors gun is an anti-aircraft autocannon designed by the Swedish defense firm Bofors. It was the most popular medium-weight anti-aircraft system during World War II, used by most of the western allies as well as various other forces. They remain in service to this day making it one of the longest-serving artillery pieces of all time.
