I cannot give you a definite answer, as , at that time, the avenue did not come under Birmingham and thus there is no listing of occupants by street in Kellys, only by name and business. This makes it almost impossible to determine changes in numbering. However , in 1888 the Avenue only went up to where Roberts Road joins it, so it is likely that (probably certain), when the street was lengthened, renumbering took place.
