No reason not to call an instrument in B Flat; historically they more 
often used terms like alto, tenor, followed by hexachord syllables, 
then "pitches". The reason is that they used a transposing system.
So if you really want to think like they thought, it is better to 
think in a transposing system, but even though I can transpose 
anything, I still have trouble making that total leap, so for example 
there are four theorbos here tuned a half step apart, I never think 
that one is in F sharp,
But the 465 instrument is a "G" theorbo for the vespers and an "A" 
theorbo for Scarlatti at 415, the 440 instrument is a "G" theorbo for 
modern opera or 440 vespers that couldn't quite get up to 465, and 
the 392 theorbo is in G for French music or even in F for singers at 
Festivals in which the pitch has been set at 440.

So each instruments letter name depends on the mode, and each 
instruments number name depends on the gig--the A theorbo is at 465 
if playing the Vespers and thinking in G.
So even though there is no reason not to call it an F sharp 
instrument, I never think in F sharp. But I do think in B Flat, even 
though that is a fairly rare transposition it is one that I have 
studied because historically, musicians were required to transpose by 
tone, third and fourth.
Theoretically, F sharp is a minor third transposition from A, but the 
ones normally used in the third transposition are G goes to E in 
minor, G goes up to B Flat in Major. I never bothered learning the F 
sharp transposition, although I was asked once to sight read a Handel 
aria with a countertenor making the transposition to F sharp minor. 
It happens, maybe better to sit it out.
