An awesome font of knowledge and information! Truly a great TM thread drift and no mention of fish!
Ray, I don’t remember the Pwll trolleybuses as I am still a spring chicken! Eynons buses were my transport back then. A family owned local service based in Trimsaran Second hand buses ( double deckers) that they left the original bus company signage inside. I remember Plymouth, London buses. They all developed dents in the nearside upper corner from overhanging branches in Stradey woods! Occasional trimming was done using an open top double decker and saws/loppers. They also did a parcel delivery service. Paid a “fare” and recipients would meet the bus to collect. If you were a regular commuter they would wait an extra couple of minutes if you were late.
