There was a Tomahawk II that was designed by Larry Kruse. It's bigger than a Veco Tomahawk, not Classic Legal, but then there's no rule that allows disqualification in Classic for indiscretions in building. And it's kitted by Dare Design, in NJ, maybe. Nice plane for a modern .25.
I can't 'splain the plans, but they likely came from the John Pond collection. Those plans were largely redrawn by hand, and were not done by modelers, but by draftsmen (Navy?) as time fillers. I read that John Pond was their supervisor or instructor, or something. Anyway, their efforts were not always top drawer (pun intended). And/or inaccurate, and often lacking needed information. Many were also blatant copies of kit or magazine plans, so it's hard to predict what you'll receive.
I'd also suggest the Brodak plans, if you want the authentic Tomahawk. It might be slightly different, but should be close enough to satisfy almost everybody. I have a CLC kit, and a Veco .19 to put on it. It'll be my first real Tomahawk, and I think it'll fly real good.
