Hi, cant tell you too much regarding pitch, have found out its an anglo, i did a test by inflating and compressing the bellows and pressing a key, the note changed and have been told it indicates it being an anglo, thats about as much as i can tell you on the playing aspect, its been in my family for a long time, it was my grandfathers fathers, given to my dad and has since been passed on to me, i can add more pics and can describe it more if you like, i have had several good offers so far, thats about it really, regards Larry
