Does anyone by any chance have Gunnlaugur SE Briem's ​​article about the Icelandic thorn and eth saved? After his website was gone, I used to find it on
sites.google.com/view/briem/design but now it's gone as well...

UPD: thanks to @bramboeck, the article is found: https://web.archive.org/web/20090129115718/http://briem.ismennt.is/2/2.1a/2.1.1.thorn.and.eth.htm
