[David_Hayward (RIP)]

Max, I have a note of your truck already! This is the complete 1942 C.15 database that I have:

2842100047S [SYDNEY-ASSEMBLED?]
2842100100 [HOLDEN-ASSEMBLED] PRESERVED
2842100244M ENGINE # SR3,779,671 [MELBOURNE-ASSEMBLED?]
2842100317M ENGINE # PR3,835,385 [MELBOURNE-ASSEMBLED?]
2842100508S ENGINE # WR3,815,503 [SYDNEY-ASSEMBLED?]

28421000919 ENGINE # SR3,851,790 WO12 (WIRELESS) HOLDEN-ASSEMBLED
2842130xx ENGINE SR3,853,267
2842131045
2842131140
2842131409
2842131421
2842131482
2842132593
28421M40750 ENGINE # PR3,835,432 [MELBOURNE-ASSEMBLED?]

I have yet to come across any Brisbane-assembled CMPs or any Adelaide-assembled ones for that mater, but here is a rare known Perth one:
2844400189P ENGINE # WR3,859,926 MAY 5 1944 [note "P" at the end of the serial number and contrast it with:
28443P00264 ENGINE # PR3,875,501 ASSEMBLED MAY 1944 [where the "P" is after the model number].

Having said that, in post-war years Brisbane did not use "B" as a Plant Code ["A" was "Adelaide"], and used a shortened Model Number.
