I too just discovered this thread. Too cool! And as the young kids say "YO DUDE"! Very excellent work. The 1/4 scale plans are a real find. I've looked for years and have collected just about everything from 1/5 all the way down. I tried the link you listed several years ago, but "Page not Found". I've collected all the well known scale drawings, Matt, Hirsch and others, including one of unknown origin and had planned on doing what you're doing- build it! Your thread will kick me into action. I also have several in depth articles from about 40 years ago, if you want/need documentation, let me know. I have a young computer geek who can compress the drawings and articles for email. You've done some real heavy lifting with this build, and if you don't mind, I'll use all your ideas so I don't have to re-invent the wheel. I look forward to the end game. Best regards, Randy
