From as near as I can gather this is an ANTIQUE FRENCH CORNET FROM COUESNON, made in the earlier part of the 20th century. It’s very good and totally original from the Couesnon workshop in Paris. This one’s quite unusual, in that all parts are original and unaltered, there are no dents or dings, mouthpipe and mouthpiece are all original. Original brass valves are still very tight, work quite well. The instrument appears to have been played very little in the past 80 or so years. The bell’s stamped “Exposition Universelle de Paris / 1900 / HORS CONCOURS / membre de jury / COUESNON & Cie. / fourinsseurs / DE L’ARMEE 94. RUE D’ANGOULEME PARIS . This Cornet includes a case and 2 mouth pieces. One of which I believe to be the original.After responding to the first question below I noticed the actual pineapple engraved on the bell. The number in the pineapple is the number "3". I am sorry for any confusion this may have caused. I inherited this horn and know little about it.
