Not many folk realised this, but in 1971, Western Welsh took delivery of 20 Bristol RELL6Ls.
They were registered UKG 801J-820J, and given fleet numbers 801-820.
All were identically-bodied, again by Marshalls of Cambridge, and to the ultimate BET Federation outline.
The chassis was specified with the Leyland 0.680 engine option, and remotely-mounted 5-speed semi-automatic transmission.
All were OMO-equipped.
801-805 were initially allocated to Crosskeys (grey diamond), and were regular performers on the lengthy 303 service to distant Tredegar. 805 is seen here at Cardiff Central Bus Station awaiting departure.
However, 806-820 were not licensed by Western Welsh.
Together with 801-805, the entire 20 were soon transferred to South Wales Transport during NBC's major re-organisation of it's operations within the South Wales area. They were variously allocated to SWT's depots at Gorseinon, Neath and Swansea (Brunswick Street). The Neath-based ones were thence regularly used on their 'mountain' service which linked Swansea, Neath and Maesteg.
