You could call them "big boys' toys", but restoring old-time military vehicles takes dedication, patience and a magpie's ability to find things - often all over the world.
Grant Moreland will be showing one of his restoration projects at the Frankton Thunder festival in March.
His most recent showpiece is a 1940 Morris "gun tractor" which had served duty for many years as a "gate guardian" at the Papakura Military Camp until rescued by Moreland.
The vehicle was ex-New Zealand Army and was in one piece, an uncommon condition for military equipment which generally had a life-expectancy measured in weeks. It required a complete overhaul.
The vehicle is "underpowered'' by a 3.5 litre four-cylinder flat-head engine backed by a four-speed transmission. Its matching limber - a form of trailer towed behind the gun tractor which carried the ammunition - was sourced from Australia, in bits, and also restored.
