Subject: Pontypridd UDC 70 (STX 106), 71 (UTX 492) and 69 (STX 105) Chassis: Guy Arab IV 6LW Body: Roe H33/25R Location: Glyntaff depot Date: 29–Jan-1972
Numerically the first three of the Arab IVs, 69 and 70 are in the light blue livery which the UTX-registered batch including 71 never carried.
69 has a weather strip at the top of the windscreen which would appear to be an attempt to replicate the “sun visors” fitted to the Bristol Ks, which I believe was more a way to weatherproof the hinge at the top of the windscreen.
