This old horn arrived in my shop to have some dent”al” repair. While I mostly work on telescopes, a challenge is always in order. Caution must be-used as you can easily  cause more damage than you had before. Technics are the same for removal, turned lathe slugs of brass and aluminum which are forced fit into the openings, ball bearings of all sizes that are sometimes driven through with compressed air. It basically comes down to years and years of experience.

horn sideKurt Armbruster is wondering what all the noise is about.
