coldstream ptl009z condenser coil required

Hi all

I have been asked to refurbish a freezer cold store. The main problem is the fins on condenser coil are extremeley corroded, but the rest of the unit is in fairly good condition. The customer has asked for a replacement to be fitted. The outdoor unit data plate states it is a coldstream rapide model PTL009Z & 21.

does anyone have any information of where i can order spare parts for this products.
