South Vietnamese ammunition manufacturers pre 1975

Is there any info available on South Vietnamese ammunition manufacturers? I mean the period before the 1975 communist victory.
There it would be interesting to hear about names and locations, used headstamps or other markings indicating the factory.

Alex,

Brian, thanks a lot! I forgot about that old thread since my questions and thoughts on this did not exist back then.
Will post my question in that thread then.

Also great to see the doc explaining the QC-G !!!
