Lemon squeezer hats identify these chaps as New Zealanders. The white fern leaf on a black background is the divisional sign for the 2nd New Zealand division. I can't make out the numeral on the unit serial, is it a 3 or 9? In 1940-41, 3 was the serial allocated to 4th Field Regt, NZ Arty amd 9 was allocated to 7 Field Company, Div Engineers. I can't find another period when both 3 and 9 appear in the lists for 2 NZ Div, but each crop up from time to time. However, without an accurate date of the photo, it would be hard to identify the unit because of these changes over time. For example, by the time the 2nd NZ Div arrived in Italy, the unit serial 3 was allocated to 36 survey battery.
The line of trucks look like Morris's, perhaps someone more conversant with those could offer a suggested date?

Re my previous post: does anyone have any issues with the description of a "37mm single shot Bofors"? It's not something I've heard of before and I was hoping someone might recognise the artillery piece.
