the Vintage Plans link

Greetings. I'm liking the Honeymoon trailer from the Vintage Plans link at to top of the page.

How does one go about getting the plans for this or any of the trailers listed?
I did try to blow up the Honeymoon image on our Mac, bring it to a scale using a ruler and then trace the image onto graph paper. It was successful to a point but not exact. I realize that I could fudge my drawing(s) a bit here and there and be content with a close resemblance. I'm just wondering if there have been any updates or upgrades to the Vintage Plans. Maybe they are just meant for reference. Dunno.
Thanks,
