Hi Ragga, information from my Father-in-Law who grew up in Percy Road as follows:
Offices on the left hand side are part of Serck Radiator company, gap between houses on right hand side, where the Wall's sign is, is the start of Colebrook Road. The van behind the bus is a Hawley's Bakery van. The yellow wall sign at the top of the photo is the start of Albion Road. In the distance to the left of the back of the bus is Greet J&I School. Also the green colored building which juts out from houses on the right is St. Bedes Church. The building behind St. Bedes was occupied by a blacksmith. Sometimes from the classroom adjacent to Warwick Road we could see a display of sparks as the smithy " worked " his hot metal .
I hope that this information is helpful, do you have any information on the date of the picture which we think late 1950's / early 1960's or the photographer ?
Rob.
