Some people were we lived put name plates on their front doors but I don't think this became part of the 'official' address. It was very helpful though when, as Falkyrn says, you were inside the building and couldn't fathom which flat was on the left and which was on the right.
On the subject of using odd and even numbers, the places I know in Glasgow use this system BUT I don't know about old Anderston. Try emailing the archive staff at the Mitchell Library I have found them excellent, very keen to help family historians.
