The first and second edition Ordnance Survey (OS) maps (1884, 1888 & 1901) depict the site as a series of fields adjacent to the Great Northern Rail, Newark and Bottesford Line. The works first appears on the 1915 Ordnance Survey (OS) map, labelled as the Lowfield foundry (iron and brass) and is depicted as a series of buildings. A newspaper article suggests that the works date to 1899 and belonged to James Simpson & Co (Newark Advertiser, nd.). The site was connected to the Great Northern Rail, Newark and Bottesford Line by a siding to the south. This siding then split to connect the buildings of the Flowserve site. The western end of the office block range (Building 2) and a large workshop forming the eastern ranges of the current workshop are depicted on the 1915 OS map. The 1930s OS map show no visible change to the surveyed buildings within the site and it is not until the late 1950s / early 1960s that the workshop is shown to have been extended eastwards. By this point, a single rail siding still passed through the western range and terminated adjacent to the southern end the eastern extension. By the time of the publication of the 1970 / 1971 OS map the rail siding is no longer depicted and the eastern range had been extended to its current extent. The eastern L-shaped extension to the office block (Building 2) had been constructed as had Building The site remained unaltered until the demolition of the buildings to the west, post-2007. The works operated as an engineering works specialising in pump products until its closure in 2016. (1)

One large multi-phase warehouse (dating from 1899) is broadly C-shaped in plan. All elevations of the building have been clad in corrugated, aluminium sheeting. A red-brick pier, with blue engineering brick details survives in the south-west corner of the building. This pier formerly formed part of a building located to the south which has since been demolished. Internally the building is subdivided into five areas. The first is a large range extending down the western side of the building. This range has a pitched roof with steel, double fink trusses. At the northern end of this range there are larger doors above which is a relieving arch constructed from three rows of brick headers. Along the eastern wall are a series of blocked arched windows. All surviving windows of this section were modern UPVC replacements with the exception of those within the ‘MOD’. At the southern end of this range a number of machine parts and bases remain. The earlier buildings hold some historic value as they contribute towards an understanding of the early history of the works. This contribution is limited as these buildings have been substantially altered and their contribution to the early site is difficult to discern as a result of the loss of many of the works original buildings with which these buildings would have been associated. As such it is considered that these buildings are of low heritage signifi-cance. Archive deposited at http://ads.ahds.ac.uk/project/oasis/. (1)
