Hi All, I understood that 'flat packed' meant parts ready for assembly. This would be compacted and crated for shipping. Perhaps about 300 arrived in Western Australia in one ship. The chassis is rivited together and could also easily been assembeled with fairly simple machinery. The body is screwed and spot welded - again not complicated. My truck appears to be as per the 1942 manual I have with only small variations.
My chassis does not have a serial number (I sandblasted myself so should have seen if one existed).
Jeff (Dayboro) - I remember seeing a web page with a Chev optionional steel tray. I will post address when I find again.
Attached is my 1942 Chev in the 1960's and more recently prior to restoration commencement.
Regards, Eric
