Some manufacturers (Chickering especially comes to my mind) leave very 
little space between the Scylla of the belly rail and the Charbydis of 
the V-bar/agraffe arrangement. Overcentering of extremely worn treble 
hammers can certainly result in hammers hanging up on the V-bar. First 
try replacing one of the offending hammers with one of the proper bore 
length (i.e. with a proper amount of felt at the striking point). You 
may find that it works perfectly where the worn ones jam against the 
plate.
