I have a 2008 MAN Plans Guide - the Antic is not listed.
Eloy,
The Antic was (and still is) a kit put out by Proctor Enterprises. I don't believe the plans were ever made available separately for the scratchbuilders. With all of the specialized (i.e. difficult-to-find) hardware required for the build, such as the many micro turnbuckles, starting out with only plans would likely become a frustrating exercise in resourcefulness!
