If you go to

Click on the left tab that says Produtos. Civil arms are what your looking for.
You will see that they still have the 669 and the 689.
I used to own the 6 in. barreled 669 and liked the gun. It however was traded for a newer then 6 shot, 4in. barrel 66.
The below is from the Taurus Brazil site. However the pictures would not come with the data.
