If I were you, I'd contact the Honorable Company of Horners, who keep the traditional horn-making methods and skills alive today, and explain your situation and see if they might run the pictures and story of your horn in their newsletter. They have recently done a lot of good work in preserving information on old horns that were previoulsy documented and sketched, and they might relish the chance to locate another good lost horn. Despite the quality of yiour photos, the horn appears to have substantial carving on it and is probably a good quality carved horn, perhaps a map horn from what little I can see. Shelby Gallien
