By assigning to the semidetached system Mu(1)Sco the age of the Sco OB2 association (to which the binary belongs), it becomes possible to search for its initial characteristics. A model consistent with the observational data is achieved by assuming a mass and momentum loss from the system during the phase of mass transfer between the components. A table giving the initial dimensions for Mu(1)Sco is included. It is believed that the primary component of Mu(1)Sco started to transfer mass no more than about 1.4 x 10 to the 6th yr ago; the search for the initial parameters of the system is restricted to the ages corresponding to log t = 7.05 and log t = 7.10, respectively.
