[CAUT] scaling a Tyre harpsichord?

[Ed Sutton]

For diagnosis, the photo shows green corrosion on the brass string where it contacted the black iron tuning pin.

All the brass strings were breaking
in this famous make of harpsichord
because of chemical residue
from the tuning pin blackening.

Not copied is a photo of a blackened wrought iron pin. He does not name the maker. My one encounter with a Hill and Tyre harpsichord had similar pins, but so do many makers.
