I have one and Triskel has posted that he has one. Mine has three sets of steel reeds and is in the key of Aflat. There are three bass buttons, two which strike the bells when one pushes firmly on the buttons, and the center one which does not. Softly pressing on the outer bass buttons results in no bell.The air button can be seen in the bass end picture. It is on the upper right in the picture.The treble pallets are made of galvanized steel sheet. This one is missing the treble grille, which is usually covered with " mother of toilet seat" in the same color as the bellows frames.I have been attempting to play Jingle Bells on it and post on TOTM but haven't gotten it perfected because the reed orientation is the opposite the conventional layout,i.e. the pull notes are the push notes. Mine is a second button pull start. Its just close enough that I have to sort of unlearn what I my motor memory is for playing the melodeon. For me, it is harder than learning to play for the first time. I just took a few pictures of mine for this post.
