The machine had 6 irregular moving pinwheels, selected from a set of 12, and the number of drum bars was extended to 32, of which 5 where also used to advance the wheels. When lugs and pins are selected carefully the C-52 provides even in this computer era a powerful encryption. The combination of C-52 and the keyboard, denoted B-52, was named BC-52. Within short time the BC-52 was purchased by more than 60 countries and remaind popular until today.
