Colleys were involved in cutlery since at least the late eighteenth century (William Colley, Thomas & Joseph Colley, Colley Bros, Hargreaves, Smith & Co, Wingfield, Rowbotham, and Manico).  Hall & Colley was first listed in 1845 as a merchant/manufacturer of scissors, razors, and table knives in Eyre Lane.  It made Bowie knives.  The company used the mark of Edward Barber: ‘CUTLER TO HER MAJESTY’.  It may have been the ‘successor’ to Colley & Co.  One of the principals was Edward Colley (a son of William Colley), who died on 17 June 1851, aged 46, at Blackpool and was buried in the General Cemetery.  By 1863, only William Hall was listed as proprietor of Hall & Colley.  The firm was in Eyre Lane until the late 1860s, with Hall the only listed partner, living in Heeley.  The firm then apparently ceased business.  William Hall, merchant of Eyre Lane, died at No. 98  Arundel Street on 3 March 1868, aged 57.  He was buried in the General Cemetery, leaving under £2,000.
