Since making my earlier posting I have located a copy of "Southwick on Wear - an Illustrated History" by Peter Gibson and on page 24 there is a photo of The Smiths Arms with the caption: "The Old Mill and The Smiths Arms were built in the 1820s. The Smiths Arms is seen here in about 1946, was demolished in August 1984 after standing derelict for four or five years, and after an attempt failed by a local councillor to have it listed as a building of architectural interest...." Regarding The Old Mill pub, referred to above, there is a photo on the same page and a note that it closed as a pub in the mid 1970s and was used forr a time as an electric shop. It was demolished in September 1981. Alan Vickers.
