Argentina - Cancellations On Rivadavia Issues (1860-S)

I have some Rivadavia stamps with muted cancellations, where I haven't been able to identify the city they come from. I used the Catálogo Especializado de Argentina Gz, which also describes the cancellations. However, the catalogue only provides a written description, without any illustrated examples, so the descriptions don't really mean much to me without seeing an actual example. Unfortunately, I don't own the 1958 Kneitschel catalogue, where this is covered in detail.

Does anyone here have experience with these cancellations and could help me identify which location they come from?
