Fork crown race too big

If a magnet sticks to the steerer it is steel, if not ally. My guess is it is an alloy steerer - but it looks a bit fooked in the pic. You can pick up good condition carbon forks for about £30 second hand so my choice would be to buy a new fork. Safety first an all.

I don't have a magnet! I'll get one tomorrow, thanks.

I wanna solve this, I like puzzles and this is the new one ;)

here are some new pics:
