Brian, the fact is i do have anglos in my house and have expolored the finger board, i also have a partner Cathy Cook, and step son, Niall Boyle who are both long time anglo players, they can be heard on Concertinas and, available from my website, so naturally i have discussed anglos and 2o, 26, 30 buttons with them, so your remark was a bit presumptious.
