    What this looks like is a “debranded” Atala. The logo is identical to Atala’s, and the other details are also similar. This was common in the 1960s into the early 70s: Helium was the off-brand Peugeout, and St.Etienne was the off-brand Gitane, for example. The reason was often a minor quality control issue with the frame; if it did not pass inspection but the defect was minor, the frame was shunted off to a different assembly line, often (but not always) fitted with cheaper components, and sold as a slightly cheaper brand. That’s my take on your “Ganna”. I could be wrong.
