This is a Keystone K-7 sailboat. It measures 10.5″ long with the rudder. This is the first sailboat that I have seen that has a wooden rudder. It is machine cut so that dates it to the late 1930’s or later and the cloth sail is pre 1950’s. With that in mind and the wooden rudder I would place the date of production between 1944 and 1949.
