Saving an Olds Recording Trombone

Some of my favorite trombones were built by the company Olds. They had a wonderfully deep line of high quality instruments and this one, the Recording model, is one of the good ones... but this one has been badly damaged. A BIG dent was "installed" in both the outside and inside slide tubes. Getting the dent out of the outside slide is easy but is it even possible to remove them from this very unique inside slide tube? Let's find out.
