1851 Adshead’s 1851 map shows J Flockton’s Union Foundry as two buildings and a yard, the ground area being about 100 ft by 100 ft. The south eastern part was bounded by a bend in the River Medlock, to the north was Carpenter Street and the timber yard and sawmill of Eastwood & Tavo, while to the west was a row of ten houses which faced onto Brook Street (now called Princess Street). The foundry entrance was 60 yards south of the MSJ&A railway viaduct. The foundry is not shown on the 1849 O.S. map.

Eagle Foundry was located about 200 yards north west of Union Foundry, on the Rochdale Canal.
