Separated back, part 2

[Farrell]

Three inches??? WOW - that is some kind of separation! Tell us more. The strings must have been mashed into the hammers while at rest? The plate must have been bent quite a bit? You were able to pull it back together without cracking the plate? This is way cool. Please tell us the whole story. Thanks.
