Ahhh ...........
If ever there was a classic Western Welsh bus, then this is what we're looking at folks!
Both are Leyland Tiger Cubs with Weymann 'Hermes' 44-seat all-metal bodies, and are two examples from an order that totalled 180 near-identical buses delivered between 1953 and 1957.
Photo 2 shows fleet no 1026 laying-over at Station Square, Neath. This was one of those that entered service in 1953. The 1953/4 bodies had an angular cantrail profile above the side windows, and their registrations were HUH or JBO prefixed.
Photo 1 shows 1177 at Cardiff's Central Bus Station blinded-up for the three-hour trek westwards to distant Ammanford. It's another Tiger Cub/Weymann, and being MUH-prefixed, entered service in 1957. Note the curved cantrail profile. This route was the hourly flagship 301 limited-stop service, which extended to Carmarthen on a two-hourly basis.
If you look closely aft of the driver's window, you'll see the fleet number with a coloured diamond positioned above that. The colour denoted the vehicle's home depot - 1026 would have almost certainly displayed a red one, being allocated to Neath. Judging by the lightness of 1177's diamond, I reckon that it's fair to assume that it was orange, and therefore based at Cardiff (Penarth Road).

Phew - anyone wanna know more?
