Other possible causes :
Someone watched a You Tube Video on hammer shaping with a Dremel Tool
Someone wanted a lighter action
Mice or rat damage although there would be visible droppings - I had a Petrof studio that mice had moved into and shredded the hammers something like this
Its amazing how people "gift" pianos to others in this condition
