Hi William,
In some of the older, (early 1900's), the ringing was looked upon, as a selling feature. They used to say resonant tone, tone prolonging bridge, and similar such terms.
They accomplished this by the placement of the dampers, i.e. closer to the null point of the singing segment of the string.
I may be wrong on this assumption, so feel free to correct me if I am wrong.
Best regards,

  OK, for arguments sake, let's say the overring is not due to improper damping of the strings.  What then?  I've had a few of these instruments that just keep going with this kind of deep resonance, after all playing has ceased and all the checks for improper damping show zip.  What else could it be and can it be stopped?

    In addition to the suggestions you've already received, take a look at the condition of the damper felt, which, if original, is somewhere between 45 and 55 years old.  It's typical, especially for the single string (low bass) dampers, to respond to drying out (thus hardening), by an unmistakable "slappy-buzz" when returning to the string.  This loss of resilience could also permit the over-ring you notice.

      I have this piano I service that has a lot of over ring when you stop playing. I've tested each note to see if there is any single note that doesn't completely dampen - they all do. The pedal is also adjusted with some lost motion. Is there a cure for this. The piano is about 1950ish.
