Sergeant George Hutchinson was seconded from the Territorial Army to the Auckland Technical Development Laboratory in 1940. His role was to design defence related equipment and initially this was a sophisticated gun sight for the old ex-navy gun mountings used for harbour defence. Later equipment developments included: harbour asdic equipment, a tape recorder used for Royal New Zealand Air Force training, ravine crossing equipment and an ‘I’ testing device for checking the surface strength of airfields. After the war, Hutchinson left the Army and finished his third ‘professional’ civil engineering year at Canterbury University.
Hutchinson was a keen photographer and his photograph collection includes not only the afore mentioned equipment, but also radio controlled motor boats used for dropping depth charges and for targets and a ship testing tank sited at Western Springs in Auckland.
