Someone really did cock-up...too much tea that day perhaps?

These are all Perth-assembled:

You can see, in typical Holden Plant fashion, that the Plant Code letter was placed initially at the end of the serial number, then the stamping guy changed his mind or his colleague changed his mind or was told to place it after the model number. This dichotomy between locations etc. lasted until at least 1959.
