If I was to guess I'd say that photo was taken in Britain.
That coachwork doesn't look familiar to me. I'm thinking maybe Harrington, or Alexander. Who else did slanty windows in the UK? Isn't the roof too high for a British coach? And what's with the protuberance above the back (older UK coaches didn't have AC)? Or could it be in Australia or New Zealand? Nah, it's too green for Australia. Any sheep visible in the background?
