The top photo is of Leyland Tiger Cub 1245 - one of a batch of 24 delivered in 1959, and wearing 'as delivered' livery.
It has a Park Royal 43-seat body of the newly-introduced BET Federation style, and were the first WW buses to enter service equipped for one-man operation. I reckon that the location is Brecon Square, and being a Brecon-allocated vehicle would've sported a grey diamond.
These were delightful buses to drive, with beautifully light steering, (no PAS in those days), and also had Eaton 2-speed rear axles. When I joined the company, four of this batch were still in all-day service at 15 years old, beings nos 1243, 1252, 1253 and 1260. They were especially popular with our drivers on the intense Bridgend town services.
Bridgend also had 1249 on shed, which wore an all-yellow livery and had been converted for towing duties at Ely Works in the early '70s.
The lower shot was definately taken on Broad Street, Barry sometime in the early '60s.
Barry-allocated 1495 was working one of the cross-town services, and the route number should've displayed '349'. It was one of around six similar buses delivered in 1959, and again of the ubiquitous Tiger Cub/Park Royal combination. This batch were sumptuously-appointed 41-seat dual-purpose vehicles, with amazingly-comfortable suede-covered seats. It should have displayed a black diamond.
