green hammers

[okoie]

Hi friends,
In a piano I wanted to buy I have seen some hammers of the bass trings green-coloured at the striking point.
Someone  can explain why ?
Must I exclude to buy this one ?

Thanks in advance

Oh, one of those pianos. Probably because the zorgog alien from the planet zartron-9 slobbered all over the hammers with his green saliva, causing a disturbance in the chemical properties of the hammer.

Console bass strings are wound with brass or copper wire to increase the weight per foot.  This makes the bass strings shorter and fit in a 40" or 44" wood box.
If the piano has been exposed to humidity, the brass or copper could corrode and stain the hammers green.
I buy used pianos based on sound the responsiveness of the action, and passing of some other tests I've listed in https://www.pianostreet.com/smf/index.php?topic=56680.0 and others
I certainly wouldn't pass up the right piano for a little corrosion on the felt.  I might say something to the seller about it to soften him up for the price I am going to offer.  I don't pay anything like the prices on e-bay.

That is probably a little more likely than the green saliva alien monster.

Time to change the striking pads IMHO...
