Rare New Zealand Farmers Union Membership Badge

An old enamel on brass membership badge for the NEW ZEALAND FARMERS UNION. The badge is at least 65 years old but could be 100 years plus as the KaitaIa branch of the Union was first formed in September 1899. In 1945 the Farmers Union ceased to exist as such when it combined with the Sheep Owners Federation to form FEDERATED FARMERS OF NEW ZEALAND. This badge is the first one I've ever come across.
