The plastics of the 1940s to 1960s were produced in a variety of styles and colours and while never specifically named by Conway Stewart, they have become known informally by collectors by names such as cracked ice, herringbone, tiger’s eye and crosshatch and the more common marbled finish. Of particular note is the model 22 which was produced in the 1950s in a floral pattern. This was produced in very small numbers compared to other models of the time. There is some uncertainty as to the number produced; estimates range from 200 to 2000.
