A certain John Palmer initiated a line of coaching Inns i believe between York, Bath and Bristol towards London ( i'm not 100% sure about the venues). This Pipe comemmorates the Highgate Hill 'branch' and the inaugaration of R Wittington as the 'Thrice Lord Mayor of London' born in 1350/60?. I suspect these pipes were given to travellers who may have stopped at the Highgate Hill Inn on their journeys to and from London as a 'Freebie' or as a promotional or advertising token from the proprietor (John Palmer) as can be seen on the pipe's stem. I know that the coaching inns is historically correct as the post office issued a set of stamps celebrating the anniversary of J Palmer's original plans for this venture. I also have a set of these stamps in my collection.
