This is a timber-framed, steel skinned sedan car body from a 1928 Chrysler. It was made and sectioned by the famous Australian firm, Holden's Motor Body Builders Ltd of Woodville, South Australia, to show its construction and the various types of timbers used at the time. These included Queensland maple, Pacific maple, cudgerie and southland beech.
By the late 1920s some 200 pieces of timber, bolted, screwed and glued together, were required to build just one car body. By the mid-1930s cars became more streamlined and in 1937 Holden's (by then General Motors-Holden's Limited or GMH) released the uni-steel turret top body, the first Australian-made all-steel car body. This was a huge advance on the timer bodies as it was only constructed of four pieces of pre-fabricated steel shaped by giant presses and spot-welded together. These steel sections formed a stronger, lighter and much cheaper body than the complex timber ones.
The work required for the construction of a timber car body like this Chrysler was much like that needed for an intricate piece of furniture or a horse-drawn vehicle. Many of the early motor body builders were previously coachbuilders.
