I don’t know who makes that particular instrument. The button pattern is the same as the Hohner 3-row (31 buttons) as opposed to what is sometimes called the Gabbanelli style (34 buttons), but that instrument isn’t a Hohner. I don’t think it’s a Weltmeister either. It could be a Chinese instrument. It looks like the player had to replace one button along the way. I see there is a single black button. In any case, he does a nice job on that huapango!

That’s a really beautiful instrument! I love the round white buttons against the gleaming red body.
