I acquired this fine wood John McCann Venetian cornettino in the early '80s. I did not play it much, and in 1984 I stopped playing professionally, so the instrument is in excellent shape.
It has two mouthpieces, one horn, the other brass, and a wonderful sound. It is covered with leather with McCann's excellent Venetian leather ornaments. It may be made from boxwood. The brass mouthpiece is similar in shape to regular cornetto mouthpieces rather than being like a trumpet mouthpiece. Bottom note is D, top note is up to the skill of the player. The sound is excellent as it is with all John McCann cornettinos, and there are no cracks in the wood.
This instrument is in almost perfect shape. It was played very little, has amazing Venetian work on the leather, and plays extremely well.
Here are a number of pictures of the instrument:
