Ah, found it. Seems the old links are broken, and the site was redesigned, but the thread ID remained the same and I was able to build a new URL:
Gemeinsamer Baubericht: McDonnell F3-H2 "DEMON" in 1/33 - Bauberichte / Construction reports - Kartonbau.de - Alles rund ums Kartonmodell
It's a little slow to load the pics, so I haven't gone through it all yet, but it does seem that some of the issues have been fixed, so hopefully this will be a trouble free build...
