Steven,

Many thanks, really useful. I already had electronic copies of Bland 1727 (2nd Edition) and 1759 (8th Edition) plus a hard copy (Ken Trotman reprint) of the 1762 (9th Edition). Thanks to your post, I now have the 1743 (5th Edition) as well, plus the other two 1753 and 1757 manuals which I had not come across before. My electronic 1759 edition seems to be a (Google?) download in two volumes and not the separate chapters from the 1st Royals website in your link.
