I am not certain if Brastemp is an off-shore Whirlpool subsidiary of some sort or if the machines were built under license, but they were made in Brazil. Production ran for many years, beginning in the 50s I believe and ended in the 90s. Belt drive machines continued for several more years at least in Brazil than in the U.S.
Brastemp and their suppliers have been the final source of many replacement parts for U.S. made belt-drive washers. The last replacement transmissions came from there, as do the two and four port pumps today (the blue-bodied ones).
It's odd that some of the more recent innovations in belt-drive machines did not see production in Brazil, including (I think) the basket mounted filters, the short centerposts, and the three-port high-volume pumps (which were by far the loudest of any belt-drive pump).
If anyone knows more about the relationship between Brastemp and Whirlpool, I'd be very interested in knowing.
