I remembered that service 160 used to have majority Hino RK176 buses and also a few Hino HT228KA buses.
Service 167 also had some Hino RK176 and Hino HT228KA buses whereas service 161 and 850 used the Nissan U31 RCN buses. Those Nissans then went down to serve the amended service 167 in 1993 bus rationalisation if I am not wrong
