Bradley, Foster, Rastrick and Co
1817 The partnership of John Urpeth Rastrick with R. Hazledine, T. Davies and A. Brodie of the Iron Foundry, Bridgnorth was dissolved [1].
Rastrick moved to West Bromwich to work on his own.
1819 Rastrick was the resident managing engineer of a new company, a partnership with James Foster. Rastrick moved his family to Stourbridge
1819 James Foster went into partnership with John Urpeth Rastrick to expand John Bradley and Co's involvement in machinery production. John Urpeth Rastrick became the managing partner in the firm of Bradley, Foster, Rastrick and Co, iron-founders and manufacturers of machinery, at Stourbridge, Worcestershire, taking the principal engineering part in the design and construction of rolling-mills, steam-engines, and other large works[2]. The works were built alongside the Stourbridge Iron Works.
1821 A new foundry was built to cope with the expansion of the business. The company produced: bedsteads, cooking plates, wheels and tools, rails and railway sleepers.
At some point became Foster, Rastrick and Co.
1831 Foster, Rastrick and Co. was formally dissolved on 20 June. The assets were transferred back into the Stourbridge Iron Works with the foundry business continuing under the management of John Bradley and Co where James Foster was the major partner with Collier and Henry Bradley.
Presumably at some point this became John Bradley and Co again.
