Grensers are good looking flutes,and versatile-shame that Rod’s list doesn’t have images.
Lots of repro. makers do Grenser models-I’ve just been checking them out on Folker and Powell’s site.
Yes, very dependable 3rd octave, as Rod says, i have no problem at all getting to high A. Other flutes have fuller sound, but i think the H Grenser is a good all-purpose flute. If one day i find myself playing a lot of Baroque, i’ll buy Rod’s Bressan model too. What a gorgeous sound it has!
Glauber says that A=385 is common for a baroque flute.I am yet to see a reference to flutes so low .Quanz I believe used 390.A reference to these super low pitches would be fascinating .
Sorry ,Herre QuanTz . I have got the ‘T’ on my keyboard working now !
I haven’t found documentation for A=385. I was probably thinking of A=392 (1 tone bellow A=440). Renaissance flutes were pitched often at A=408, if you consider that the lowest note is D, or A=460 if you consider it to be C. I think the tunings we use today are for convenience sake:
A=415 = 1/2 tone bellow A=440
A=392 = 1 tone bellow
A=360 = 2 tones bellow
But i’m not a specialist in these things, sorry. You probably know the same or more than i do. I just play them things. 
Just to add info on the pitches, this is how Philippe Allain-Dupré summarizes it in the “earlyflute” Yahoo group:
HTH…
