Haddorff piano in Seeburg B #56,714. The serial number is rubber-stamped in the little rectangular frame between bass and treble. The plate is made in two pieces, with the lower part originally painted gloss black as shown here. The tuning pin area of the pinblock is exposed, but the rest is covered by the separate gold-painted upper plate. This piano was installed in thousands of Seeburg instruments from 1909 through 1921.
