More Rs were w/d in April 1976. These included the last R700s in Dublin - R791 and R792 in Summerhill. These were unique buses (along with R798) , having autotransmission, so they were precursors of the RA. They were classified OPD2/2.
Also to go in April in Clontarf were R814/6/9 820/1/6/9 831/2. This left only R812/3/5/7/8 822/3 830 in service in May. They were almost exclusively on route 30 by now. See separate post about RAs in Clontarf, which replaced these Rs.
