Zeno, thanks for your thoughts on the Triotar. A 3 element lens sounds rather primative by modern standards, but that said I like the character of the Holga's simple meniscus lens, and sharpness edge to edge is vastly overrated don't you think.
Regarding your book, yes it would be most helpful to have it sourced within the EU. (And PS I would dearly like the UK to stay within the EU, or at least the customs Union. Madness not to do so.)
