Günter Körber was a prominent maker of Renaissance Woodwind Instruments, especially know for his krummhorns. This Bass flute is tuned to A = 440 and the tuning is quite good up to the 2nd F (would be 2nd B on a D flute), I only manage it about 10% of the time. The next F# up is OK and the third G does play well (that’s as high as I ever go).
Here is a link to YouTube of a Körber Bass being played: http://www.youtube.com/watch?v=SPM4Mn4OTCU
The Bass flute is 91.5 cm in length, the bore is 2.45 cm in diameter and the outside diameter is 3.55 cm. The left hand finger spread is 8.5 cm and the right hand finger spread is 8.8 cm. The third finger toneholes for each hand are drilled at an angle to shorten the reach and located in an ergonomic arc. The flute is surprisingly light, weighing only 485 grams (lightweight Rosewood and a BIG bore/hole). Overall the flute is certainly massive, but light enough and fairly comfortable to play. I can play for half an hour without discomfort. 
Playing the Renaissance Bass flute is a bit different. All Renaissance flutes seem to require a softer blow with a fuller embouchure. The tone is gentle and sweet with an easy upper octave. But this flute can not be driven hard like a good Irish Flute. The bottom G is certainly a bass and comes out full and deep (like a hard bottom D). Lazy fingerings do not work on this flute, little quirks like RH3 down on C# (F# on this flute) will ruin the note…
The only “issue” I know of is, the tennon is a bit ovalized, but the wood is supple and it assembles easily and securely.
Feel free to ask questions, but be warned I really know nothing about the playing of Renaissance music (I’m just a curious cat).
