Hi David
Welcome to the forum, I can't be of much help other than to tell you that photos of the old Arthur Street are notoriously hard to find. I have only ever seen two or three in the last decade or so. Those are probably on this thread of you look back or just type Arthur St into the search box at the top right of the page.
Arthur Street as it was has completely disappeared now, on fact a good part of it has been renamed Camelot Way (why?) Number 311 would have been somewhat opposite the bottom of Herbert Road on the now playing field of (Oakley Road School) Holy Trinity Catholic School.
