Negative in a Ferrania Canister from Belair in South Australia

This negative was found in Belair, South Australia, inside a Ferrania canister. It was accompanied by a Ferrania Alpa camera c. 1945. I thought that the negative was shot in this camera, but that was not the case as the camera uses 127 format film and the negative is medium format (type 120). There are no edge markings on the film that could help in identifying the manufacturer and the year of production. If it was made by Ferrania it would be either Pancro or Superex Pancro.
