Ortho Litho films

A quick series of related questions:

1) Is Freestyle's Arista APHS Half Tone Supreme Ortho Litho Film the same film as Nacco's ortho litho film?

2) If so, which Nacco film is the equivalent, H-80 or H-87?

3) If so, does Nacco sell in small quantities to consumers?

4) Also, what company or companies actually make these films?

Thanks.
