@Ken Fraser I also have one paperback copy for use, and another from the 60s, a beautiful hardcover that I only use when I need to see more details (it's a bit bigger reproduction than the A4 one ).
I also love the Dutch writing masters, and the earlier English ones … Shelley for example has sublime exemplars … for all who don't know it already, @sybillevz has a wonderful website with tons of information and links to most important copybooks from the 16th to the 20th century … https://pennavolans.com/
Thanks for the link.
I'm a big admirer of George Shelley. A different, earlier very beautiful style.
A couple of years ago (on 4th June 2017) I posted an example of my take on his writing, here in the Copperplate category. I would post a link, but I don't know how to.
( It's titled "In the style of George Shelley".
If you are interested, a search under "Shelley" finds it.
Of all the wonderful examples of calligraphy I've enjoyed over the years, my favourite is the page titled "Honour" by Willington Clark in the Universal Penman. (exemplary penmanship superbly engraved By Bickham.)
