Someone tried to bend it back in shape with their fingers. I see
fingerprints around the damaged area in the second photo.

This Youtube video shows how a trumpet is made
The part of the video that shows how the damaged horn can be repaired starts at 1:38

The hammering part at 1:40 might be doable as a repair attempt, but there's
no way you can spin the trumpet In a lathe. You'll note that all of the
lathe work was done when the pipe was still straight. It was the lathe work
that smoothed out the hammer marks.
