The Steinway & Sons Model L is among the larger sized Steinway ‘baby grands’. The Steinway Model L scale design is based very closely on its predecessor the Model O. The Model L with its square tail, was designed to replace the same-size Model O which featured a rounded tail. The cast iron plate and soundboard conform to the square tail providing additional soundboard space at the rear of the instrument when compared to its predecessor. The Steinway Model L was manufactured from 1924 until 2005.
