| This horn is marked "Made in Italy" and was no doubt made by Rampone and Cazzani, Milano. It is an inexpensive student horn imported by a variety of vendors for the public school market. It is a "compensating" double horn. This means that the upper and lower valve slides are combined together in pairs to "compensate" the lengths for the F horn, while for the Bb side only the upper rank of valve slides is used. The compensating horn was the first double horn as designed by Kruspe in 1898. On the later full double horn pattern the F and Bb valve slides are totally independent. | ||
