This is a very early piston horn made by Couesnon Paris 1886. Lovely ornamented. The horn is very much like a natural horn, same crooks as the “cor d’orchestre”. Bb alto, F, Eb and D are with this horn. The Bb crook is a new crook fitting this horn like a glove. For lower crooks the piston slides need to be pulled out.
