Sima CT-2 vs Sima CT-200 difference and photos

[Cyclone82]

Does anyone know the difference between the Sima CT-2 and Sima CT-200 and is there a way i can tell which is which? I am trying to find the Cypress equivalent (cYpress is the factory that made the Simas) and i can get a Cypress one but i dont know if it is the CT-2 or CT-200. Is there any way i can tell whcih is which by functions or photos? the Cypress does not have a part number on it.
