I have searched all through my collection of photos in search of an image of 1111 Coventry Road and these are the two best images I can come up with. The first on is taken from Kings Rd and the block of houses your cousin lived in would be the second on the right. In the second photo the block is immediately to the right of the photo.
I'm only sorry that neither of the photos is very good, but I will continue to look for better and of I come across anything better I will post it here, so keep an eye in the thread. It doesn't matter how far away you cousin lives, if he owns a computer or some way of accessing the internet then advise him to join the forum he can then check for himself. Computers are a great way of making nostalgic journeys without leaving your own house.
