A note on tuning. In designing his instruments for maximum playability Engelbert Schmid made a decision to raise the pitch of the Bb horn in the range from second line G to the C below. This necessitated slightly raising the the pitch of the same G on the F horn, so it may be a little higher than you're used to.
