Debate remains as to when MG car production started, although the first cars, rebodied Morris models that used coachwork from Carbodies of Coventry and known as "Kimber Specials", bore both Morris and MG badges. Reference to MG with the octagon badge appears in an Oxford newspaper from November 1923, and the MG Octagon was registered as a trademark by Morris Garages on 1 May 1924. Others dispute this and believe that MG only properly began trading in 1925. Morris Garages assembled their cars in premises in Alfred Lane, Oxford. Demand soon caused a move to larger premises in Bainton Road in September 1925, sharing space with the Morris radiator works. Continuing expansion meant another move in 1927 to a separate factory in Edmund Road, Cowley, Oxford, near the main Morris factory, and for the first time, it was possible to include a production line.
