Hi Duncan,
I have the Revell model of Dresden, although I have displayed it together with the WWII Graf Spee in the same display case with the title 'Raiders'. I'm in Glasgow but may be in Leven on Friday 10th September to do some work, I could drop it off to you and pick it up again some time later.
If thats any use just let me know.
I have pics of my 'Raiders' display case in my Webshots page. If you get onto Webshots you'll find the pics under my user name, Jamiemcginlay, in my 'Jamie's Warships' Album. In my 'Jamie's Historic Ships' Album you'll also see my model of the Charles II's ship The Sovereign of the Seas, which is 17th century, but I don't know if that would be suitable. I'm sure your Chillean guest will be interested in anything connected with Admiral Cochrane, but I don't have anything to contribute there...sorry!
My webshots link is:

You could try clicking on that, if it doesn't work then copy and paste it onto your address window.
Cheers,
Jim McGinlay
