[CAUT] Bass string & Aliquot bar contact noise

I'm looking at a grand piano where an upper bass string has a very 
pronounced "zing" on a hard blow. It sounds just like when a damper wire 
touches the string. But even with the damper removed I hear it.  I 
suspect it is the bass string touching the treble aliquot bar below it, 
meaning perhaps the aliquot bar is in the wrong spot, too far up the 
slope of the plate. Before I do anything like move the aliquot bar, I 
want to run this by everyone. Do you agree this could be it?

Thanks.
Robert
