C15 Wireless Van (aust )

[David_Hayward (RIP)]

A = ADELAIDE
B - BRISBANE
M = MELBOURNE
P = PERTH
S = SYDNEY

However, it appears that in later post-war years, say around 1958, Brisbane did not bother to use "B". In fact the only Brisbane-assembled CMP I know of is:

38444B00073

So the one you have just mentioned could be a Brisbane truck. However I know of several CMPs assembled by Holden that do not have Plant Codes, so perhaps Brisbane trucks are more common than the above might suggest? All cabs were assembled at Woodville, near Melbourne though.
