There is a useful entry for Black Hawthorn in Grace's Guide to British industrial history, which has several links and references, eg to interesting on line copies of 'The Engineer' magazine from the 19th century. (When reading PDFs or other documents, you may find it convenient to use CTRL+F and search for Hawthorn.)
I couldn't find anything concise and detailed on the web for Black, Hawthorn & Co. Perhaps we need to do something about this for all NE railway manufacturers.
