I have built a lot of fatbike forks over the years, but only a few like this (Peter's). 100mm axle spacing and 120+mm tire spacing always looks bizarre to me. But what it looks like matters less than what it does, obviously, and this will fit the wheel and tire it needs to.
Peter also notably needed a _350mm_ steerer tube. Yes, that's 14". Good lord. Hopefully he'll send a picture when it's on the bike and built up - those handlebars must be up in the sky!
