The yellow C239 Honda Motorbike & Sidecar has been identified in two production versions. One has a strong yellow base colour shell whilst the other has a translucent yellow body. The bodies would have been produced in two seperate production batches. Each production run starts with a quantity of clear plastic granules and a small fraction of colour dye granules to create the final yellow colour. Two production runs with different amounts of coloured dye would have been required to create body shells of different hues.
C239 variants are now recorded as Type 1 dark yellow, Type 2 light yellow.
