I wonder if the brass wire used in harpsichords would work? Schaff bought out APSCO, they had #7 brass spring wire in 1/4 lb coils, #1B220A07. Go back to Schaff, and ask for that number, it might be that the person who you were in contact with, was too lazy, or didn't know how to follow through. John M.
