Thanks Phil, I realised afterwards that I hadn't answered the question as to what they did. They were there as Parker & Osborne (overmantel) Ltd in 1933 and 1940. Before that in 1912 and 1921 it was Avondale Bakeries, and in 1896 John wilkinson, Rope maker and paper merchant, who presumably originally had a large part of Jakemens Walk as a rope walk
