The fork is very interesting, the blades are perfectly round in cross section, 22mm in diameter.

...are we looking at the same photo ? If you disregard the camera angle distortion, it looks like a classic straight on front wheel impact bend. Assuming it is, the most effective way to straighten it is to attempt to reverse what happened. IOW, with a hub or axle in the fork ends, to straighten by bending both legs in the same motion, in the reverse of the original bending force.

I've done a few of these. They all looked about like that if what I'm seeing is not a mirage.

Yes, definitely bent. I have a couple more forks that are bent so I will build a jig to to secure the forks while reversing the bends.

...here's the deal, and the only reason I responded again. If the fork ends are already parallel and spaced appropriately (@ 100 mm more or less) bending each leg by itself introduces a lot more variables in the process. What you are really trying to do here is to get the fork ends at about the same point realtive to the rest of the frame so that they are spaced appropriately, equidistant from the plane of center for the frame/fork, and pretty close to where they were originally to porvide the same rake and trail that was designed for your frame. Since in almost all the cases where a fork looks like yours the original bending force was a front impact (running the bicycle straight into an immovable object), the quickest and easiest way to get where you need to be is to atempt to reverse that bending force with as few motions as possible.

Back before the acceptance of a non-heliocentric universe, we used to do these by leaving the fork in the frame, but taking off the wheels. Then inserting the fork appropriately (with an axle or hub in the fork ends) upside down in between the steps or rungs of a wooden ladder, and using the frame as the bending lever. It worked a lot of the time, but you'll get much better and more controllable results with some kind of fork alignment jig.
