Catalina 350 International Association

Does anyone know which model refer the earlier model Catalina came with. Alder Barber 100 Cold Machine or 200 Super Cold Machine. I am looking onto the vent kit which has different part numbers for the two and have yet to find anything which identifies which unit is installed.

I'm pretty certain C350's come with the Adler Barbour (Waeco) Cold Machine CU100. I think the difference is that the Super Cold Machine is air cooled with a water cooling option.
