Narcisse Briais letter balance | This letter balance bears the initials N.B. of Narcisse Briais. These initials were also used as a logo by his successors, see for more information about this here. The balance has a few special features: the pressed steel main bearing bush is square and the platform supports have a closed circle. In many other balances it is a semicircle. The wooden base has four small cylindrical feet. The red felt bedding in the recesses for the weights appears to be a later addition or replacement. | back of the letter balance |
