Thanks.

My recorders have "Baroque" tuning. They are consistantly flat compared to other instruments (except if I overblow, which isn't really something I can do with the music I want to play, plus it might put me in an upper octave when I play some notes). They are made to be that way.

The fingering is as JohnB described.

We've already checked the tuning with an electronic tuning thingie. It is about a half step flat. I think this kind of recorder may be much more common in the US than in other countries. It seems to be pretty standard here with recorders bought in music stores. All of my recorders since the early 1970s have had that tuning except for the Renaissance recorders (which I no longer have, and don't know how they are tuned).

Can anybody give us make and model (or series number) information on their standard tuned recorders? The ones I have now are Aulos (sopranino and soprano) and Yamaha (alto, tenor), but I don't know what models or series numbers they are.
