Ordnance Survey Benchmark, in very good condition. Cast brass [?] set into the wall of a shop in Middleton-in-Teesdale. www.bench-marks.org.uk/bm737 This bench mark was used during the Second Geodetic Levelling, England & Wales [1912 - 1921]. It was included on the Wolsingham to Kirkby Stephen line as "Flush Bracket on N.E. corner of house, junction of Bridge Street and Horse Market, Middleton in Teesdale. " at 755.347 feet above Newlyn datum.

An ordnance survey benchmark, cut into the stone base of the wall at Molten. WD is "War Department" [in the UK, the Ordnance Survey was, historically, part of the War Office, responsible for mapping territory]. This one may be damaged, as the broad arrow should be topped with an horizontal line, which is the levelled "spot height". Otherwise it's the point at which the angled lines meet. Not quite sure of the meaning for the other marks. en.wikipedia.org/wiki/Benchmark_(surveying)
