The bus - Kowloon Motor Bus received 30 Bedford OBs in 1946 and they were withdrawn during 1959. Two different types of bodywork were carried by these OBs, one a locally built body with 5 window bays between the front and rear doors, the other featuring 4 window bays, on which this particular model is based. A photograph of the actual 4227 can be found in Mike Davis's excellent book "Hong Kong Buses - Volume Two - Kowloon Motor Bus".
