Would have to be A Smith Mini Plane I am finishing up. Not because it is a bad kit or that the wood was crooked, but because it was partially built by someone else. It was 50% built when I got it, but I have easily spent more time trying to fix mistakes than I would have if I had built it from the start. At first I thought it might have been a first attempt at building by someone, but I have decided it had to have been a "professional" job to be messed up this bad.
