Good evening Lewis, The special agraffes are offset to allow proper strikepoint since the agraffes you're describing go all the way to the top. A regular agraffe in this section would necessitate the hammer striking too far from the end of the speaking length. There are two versions of those with the threads offset by 180º. The threading for the special high treble agraffes is 5.65mm x 33 thread. Current production uses a capo bar system in the treble. The regular Bechstein agraffes are 6.65mm x 33 thread. Also note that the C. Bechstein model C & model D also use a special width trichord agraffe.
