Object detail

6 3/4" (17.1cm)
McGregor claims that his "hammer-rest will hold the hammer perfectly stationary and prevent its vibration, and at the same time will not bind so as to prevent the free working of the hammer when the key is struck... It will also be noticed that these additions do not prevent me from removing any individual key with the entire mechanism belonging thereto, if necessary." (Patent Number 113,785)
