This is a pic of Cliff's F30 or F30S [don't know when the 'S' was dropped]. Note the lack of cab vents...I believe as she is in NZ that she was supplied to Contract S/M 2003 direct to the Middle East and then issued to the NZ Expeditionary Force, subsequently being 'sold' and shipped to NZ. It would have been a British order but send SKD from Windsor Plant direct to Alexandria. Similar early British Chevrolets though had round cab ventilators. I have a photo of a very early 1941 Model C15 to S/M 2002, built early September 1940 in Aussie that does not appear to have ventilators although they may have been 'filled in'.
