That is an absolutely bizarre fork.
I have to agree with others. Time to send it to the great trash bin in the sky, and source a new fork.
All forks tend to have a slightly raised part for the crown race seat. But, that appears to be larger than I would otherwise expect.
I'd measure the bearing seat and steer tube carefully. Is it possible that that is a pseudo 1 1/4 x 1 1/8 tapered fork?
Here are the dimensions of the tubes and the crown race.
