The bersag horn, with original mouthpiece, is a conical bore bugle with one piston valve on which a diatonic scale may be played.  It has a double loop and the Périnet valve is used to lower the pitch from B-flat to F.  The valve spring is in the bottom and the main tuning slide is at the second bow.  These one-valve bugles were particularly popular in World War I, used by the Italian troops.
