I have only seen photographs myself - there was/is a really nice example on Flickr somewhere. They were made in Manaus. It must have been due to trade restrictions or import tariffs, and only appears to have been the C330F. Interesting that the 80mm lens text is in English and not Portuguese. I am not too surprised that one made it to Portugal, but I really wonder how many were made and where they were sold. I would not have thought that Brazil alone would be a large enough market to warrant setting up a subsidiary, but it obviously made sense at the time.
The 'Fabricated' rather than 'Made' notation suggests assembly, but that might just be co-incidental.
