In reply to your request for pictures of Dawlish cottages and where to get them.......
There is a vast collection of old pictures of Dawlish in the Dawlish museum which may be worth a look, alternatively I know the White hart pub had some pitures of the roads around the pub but I am not sure which way they were taken, but it may be worth popping in and asking as they are good pictures. They used to have them on the wall but have since taken them down, but I am sure if you buy a drink they would get them from upstairs......
