Prior to the creation of Parcel Post Service in 1913, only packages weighing less than 4 pounds were allowed through the postal system in the United States. Postmasters used scales such as this to determine the correct postage. Erastus and Thaddeus Fairbanks' company was one of the top suppliers of scales to the Post Office Department.
