G'day Lil Dog Turpy,

"It's a 30 button english" ... I take it this is one of those "filleted" English system instruments, with Italian "accordion" reeds (brands such as "Saga" ...) with all the repeated notes (say; G# / Ab) removed to reduce the number of keys and reeds (made originally by Bastari/Stagi in Italy ... after they made full 48-key models for Neil Wayne, back in the '70s "Concertina Revival" ... ?
