I have just also remembered that a couple of months ago I noticed a Mrs Judith Shingler has been giving the odd lecture on the Lake District etc manufacture/maintainence of Sunderlands etc, at various historical socs in that region over the few years plus 1 or 2 upcoming. Lectures were searchable on the web. Not sure if she still to be found Kendal area, hope useful to somebody.
