Antique Forbes Quadruple 452 shaving mug

On bottom of mug is a circle with: Forbes Silver Co. USA - Quadruple around a second circle with an eagle head. Under this is the number: 452.

There is a removeable bowl and a holder for the shaving brush above the handle. My research places it most likely between 1894 when the Forbes Silver Co. was established and 1898 when the Quadruple designation was discontinued.
