PLEASE SEE MY LAST POSTING. I AM GOING TO UPDATE IT, AS I HAVE TIME, USING THE LIST I HAVE ALREADY STARTED.
My Criteria for this list is for companies that have had their own headstamps, or headstamps made in other countries with the headstamp of the receiving country in South or Centra America.
I am not including artillery arsenals, about which I know nothing, or explosives manufacturers, or commercial reloaders unless they had, from time to time, their own headstamp. Some entries will be very scant. If one specific caliber is all the represents a country, I will mention the caliber.
Those made in one country for another will have both countries named.
