There are probably more than a few who know already but I will be more than happy to be guided to even more useful free stuff. I have a repro. copy of <A companion to the New Rifle Musket> Originally published in London in1855. I have also 'found' this <https://archive.org/details/classbookforscho00wilf/page/n4> Bill Curtis has written some good stuff which helps me with my beloved PHE2B. Available here<http://www.researchpress.co.uk/index.php/component/finder/search?q=managing+the+enfield&Itemid=221> Does anyone know of any other useful stuff?
