I got a total of 13 expressions of interest, if I include a couple of strange pieces of related spam and a threat.
Pleased to announce that Gary Amos wins the battlefield guide (not entirely because of the blackmail attempt), and Bart Vetters wins the German-language version.
If these two gentlemen could contact me with postal addresses I'll get the books to you.
You can email via the address on my Blogger profile or - and maybe better, since I fear that BtInternet may have screwed up my email accounts again - send a comment to this blog post which I won't publish.
Thanks to anyone who sent an "entry", and thanks to anyone who was interested enough to follow my humble adventures on the Danube.
