Well, Ricardo, honestly I know nothing about them.

But it is only a guess from my side. I don't have any valid information.
There are still lots of small and mid-term companies in China who are involved at least partly in producing products for the film based industry.
For example cutting and packaging of film, producers of 135 format metal film cassettes, producers of single use cameras and normal cameras.
When I visited China I've seen lots of different film camera models from manufacturers I've never heard of before.
Models produced for the huge Chinese market, not for export.
