The one on the left looks like a Humber Mk1 or 2 scout car (only real difference was gearboxes). I'd have said Bedford from that front too... Will double check. Edit: Bedford 15CWT fine by me, just wanted to see if there was any other possibility first.
Here's an article on the Scout Car that the "Tank Boffins" may find interesting:WarWheels.Net - British Armoured Cars In Europe - 1944-1945

Great stuff - really nice that the owner's made the effort to ID every vehicle. (And plenty of FV600 types. Everything's improved by the presence of FV600s)
