vikinger: With further clues every 24 hours maybe this will become a week-long thread!
Clues ... let me think :)
When I first saw it, I thought it was strangely perhaps Welsh,
but it was actually in this Somerset pub => Plume of Feathers and once explained was obvious even to me [:D}
So as a clue, there was a plastic replica, on the counter nearby, of a Royal National Lifeboat
PS: should we disallow ringing of the publican for clarification ?
First B&O (1976) was a Beogram 1500 ... latest (2011) change has been to couple the BL11 with the BL6Ks *sounds superb*
