This headstamp showed up a number of years ago and there has been a lot of speculation on it’s origin.
Over time it has been speculated that it was produced in Syria or Macedonia. John Moss with his sharp eye thought the headstamp looked like it may have been made by CBC in Brazil, but they denied producing this headstamp, which turns out to be true.
Now we have a pretty solid identification, thanks to Fede and the AACMA. This round was made by Santa Barbara S.A. in Ecuador on equipment that was supplied by MAGTECH (CBC) so John was on the right track afterall.
