Model: Split Pin
Type: Grand
Serial: 116518
Year: 1930
Another in the series of pianos designed without relying on a wooden pinblock such as the Mason & Hamlin screwstringer and the Baker upright. In this case the tuning pin is a snug fit through a hole in the plate. On the other side of the plate the protruding end of the pin is split and fitted with a wedge, somewhat like an axe handle. The wedge is driven in just enough to provide the proper friction for tuning. No wood to break down over time and very stable tuning
