Thanks for that info Bernard, fascinating - so it's a Bass/Baritone/Tenor!

From what you say, when it arrived with him, those bottom four buttons on the LHS were already tuned to Anglo Tuning?
Interesting, I know about the common ~ low G# to F trick, cause I had that done to my own Treble, but I wonder how common this practice was of slightly Anglicizing an English?

I better stop this now, before I get a call from the C of E! :-)

Cheers,
Dick
