This is another one of my article projects, as once published in an Issue of "Sci-Fi & Fantasy Modeller". This one was in one of the special issues, related to Gerry Anderson's various TV shows. (Issue 2 of 21st Century Modeller.)
The entire article was scanned in, by the author; and uploaded, for other hobbyists to have access to -- with the publisher's permission. (But note that I'm not trying to release the article to the public domain; just sharing it.)
See the WIP / SBS link, to go to where the article's individual pages scans are stored. I believe I even uploaded my hand-drawn "working drawings," based on the as-built replica. (I've never seen the original studio model, in person.)
