I've got this Aussie bike with a bent fork. The fork is spaced too wide, and then if you bend it closed with the skewer, the wheel is off center.
Today I bought this green fork, the steerer is exactly the same length, same crown race dia, so easy swap over. The front end sits higher. Brake reach is quite a lot.
Can anyone ID the green fork? Seems pretty nice. The only marking on the steerer just says 58.

How will this ride? Is this a bad idea?

I’m sure that it will work fine. It does change, slacken, your geometry some.

Your original fork is probably fine enough for realignment. Aside from putting a wheel on the original have you checked what is off?

Eyeballing it, the fork ends are misaligned. The guy i bought it off (who had had it made for him) said his son took it underbiking or crashed it or it was a fixie or something.
I did carefully bend the rear end with a bit of wood as the spacing there was 118mm and the dropouts weren't parallel. That seemed to work ok.
I'm not confident about bending the fork, but now that i have a replacement might as well make some alignment tools and give it a try.

like this guy:
but must be easier to bend a super light 531c fork.

You’re in Auckland aren’t you?
I can help with straightening the fork

that would be great

The green fork is from a Rivendell.
