Seabourne Express tilt,Rosslare.
Where were they from,Barking?

Yes Barking. Originally owned by Clive Bourne. Clever play on his name C. Bourne = Seabourne. I believe he said that he started the business at 17 years in 1962 and his office was an East London telephone kiosk - UPS bought the company and he became Sir Clive Bourne eventually
