Hi Mike,
Sorry about the slow response, I don’t seem to get notifications from this forum.
To be honest I haven’t checked the lowest note (I don’t have the instrument, this post is on behalf of its non-playing owner), on my instruments it’s often an F next to the bottom G instead of a G sharp.
I did a rough ear check against my treble and it seems to be in concert.
The bottom “inside” note is G below middle C. I think the note next to it is G sharp but I can’t swear to it and don’t want to disturb the owner unless there is some prospect of a sale.
I think the solder on the reeds is due to its retuning from Salvation Army or some other band pitch, but that’s just a guess.
Regards,
Adrian
