Flush bracket bench mark, it is located here Image The number on the bracket is OSNIBM 1008. The mark is 14.00 metres above MSL. OSNI produced an initial run of flush brackets numbered 1001-1025 that were used c1932-1936; of these, 21 were sited in the greater Belfast area and 4 in County Londonderry. This is the only remaining bracket from the 4 located outside Belfast still in existence - the other 3 were all sited in the Toome area but have been destroyed. OSNI later used flush brackets in much greater numbers for the retriangulation and levelling of Northern Ireland in the 1950s and early 1960s. See also Image
