Unknown Maker (poss. Couesnon or Gautrot)

This is a Cornet by an unknown maker, year also unknown. It has no markings but is probably French. Many details (ferrules, pinky hook etc.) look (almost) exactly like those on my 1902 Couesnon Cornet, so I think this may also be a Couesnon (or possibly a Gautrot, as the 1902 Couesnon originally came from the Gautrot line). There is also a case in the 1912 Couesnon Catalogue that looks very similar to the case this cornet came with.

This Cornet is in very good playable condition and comes with 3 tuning bits/crooks: Bb, A and Ab.
