If the finish is contacting the speaking length=20 in front of the bridge pins, this could also be a=20 cause of short tone. It is not uncommon to find=20 instruments where a technician has 'bedded the=20 strings' so effectively that they are embedded in=20 the bridge cap. This will cause the string=20 termination to be bourne by the bridge notching=20 in front of the pin. >Hammers are quite light (4.3 g for the highest=20 >trebble, 6.0 g for note n=B060), and new shanks=20 >are already tapered in the last section. Hammers are unlikely to be the problem with=20 regard to sustain. But the sound board might well=20 have deteriorated. Check it for curve with a=20 thread underneath. Many of the 1920's instruments=20 I've inspected are due for a new board.
