In use for 6 years from 1955 through to 1960 and having 5 different variations, this box type was used for all models.
The box still had a line drawing of the model contained within but this time the ”Moko” name was in the same bold font as the ”Lesney” name. The difference was in the end flap design; more specifically the text.
