Possibly resolved the issue regards The Merry Boys, East Peckham. The first Google Street View pic of the pub, though today called 'The Merry Boys', was originally called 'The Mitre'. The old pic entitled 'The Merry Boys' is the original pub of that name located on Addlestone Road, East Peckham and is now a private dwelling. When this closed the licence and name was transferred to the present building. Compare this street view with the old pic of The Merry Boys, which will answer the issue about rising/falling land levels next to the present pub.
