List, Experienced a minor oddity today. Replaced a broken B7 treble string on a 1960s' Steinway D today. Measured the string with a digital caliper and came up with .030 (Size 12 1/2). However, the plate was clearly marked 13 1/2 as the lowest size. The string was original. Is it possible for a string to stretch itself over the years by that much and become a smaller diameter than it was in the beginning?
