From the manufacturer:
This remarkable piano was created for professional use in schools, churches and other institutions, and for anyone one who requires grand piano characteristics in a compact vertical size.
The Model 50 surpasses all other uprights in power and tone and with Mason & Hamlin innovations like the Tension Resonator, which preserves the crown of the soundboard, and sturdy 6-post back construction, the Model 50 will withstand years of strenuous use.
As with all of its pianos, Mason & Hamlin builds the Model 50 by hand, using only the finest materials, making it the best value in its class. And, as always, Mason & Hamlin pianos are Made in America.
