The Liverpool Mercury of 8 June 1881 has a list of petitions and liquidations including the following:
"W. Kinnear, formerly of Amble, Northumberland, coal fitter, then carrying on business in co-partnership with Joseph Harrison and the trustees of the late John Harrison, at Amble, and at Newcastle upon Tyne, under the style of the Radcliffe Coal Company, as coal-owners and fire brick manufacturers; afterwards carrying on business in co-partnership with the trustees of the late John Harrison and the representatives of Mr Joseph Harrison (then deceased); and now carrying on business at the same addresses and under the same style, and residing at Radcliffe House, Amble."

So it looks like the Radcliffe Coal Company carried on after John Harrison's death but with different partners.
In February 1882, the Liverpool Mercury carries a list of new registered companies including the Radcliffe Coal Company Limited, with capital of £20,000 in £250 shares.
