The World 250/5207 film is a color negative film. It is a converted film made from material for cinema film production. You could buy it online for around 7 euros. The supplier was probably a company from China.
Kodak from the USA is responsible for producing the film material. They make the daylight film as Kodak VISION3 250D. This film is actually produced in large rolls for cinema film production. The large rolls are then cut up and filled into 35mm film cartridges. This means that the material can also be used in 35mm cameras. One roll usually holds 36 images.
However, a special process called ECN-2 is required for development. This differs slightly from the usual C-41 process and is not offered by all photo labs. So find out beforehand to make sure that your film can be developed.
