Yes, the French Horns were used from 94-97. 95 is where we got new Sops, new Baris and Mellos to replace the Alto Horns.
The split that year was 8 Mellos, 6 French Horns.
Silver isn't the only color horns have been. In the 70s and 80s, corps had horns that were Gold, Silver and Chrome.
The Bridgemen marched Gold as did the Colts in the early 80s.
